DESCRIPTION  
The SP207EH/208EH/211EH/213EH devices are high speed enhanced multi-channel  
RS-232 line transceivers with improved electrical performance. The SP207EH/208EH/  
211EH/213EH series is a superior drop-in replacement to our previous versions as well as  
popular industry standards. All devices feature low-power CMOS construction and the  
Sipex-patented (5,306,954) on-board charge pump circuitry that generates the +10V  
RS-232 voltage levels using 0.1µF charge pump capacitors. The SP211E and SP213E  
devices feature a low-power shutdown mode, which reduces power supply drain to 1µA.  
Enhancements to this series include a higher transmission rate of 500Kbps, a lower  
power supply current at 3mA typical (no load), and superior ESD performance. The ESD  
tolerance has been improved for this series to over +15kV for both Human Body Model and  
IEC1000-4-2 Air Discharge test methods.

FEATURES  
Charge–Pump  
As in the original RS-232 multi-channel  
products, the SP207EH Series high speed  
multi-channel RS-232 line transceivers provide  
a variety of configurations to fit most designs,  
especially high speed applications where +12V  
is not available. The SP207EH Series is a  
superior high speed drop-in replacement to our  
previous versions as well as popular industry  
standards.  
The charge pump is a Sipex–patented design  
(5,306,954) and uses a unique approach  
compared to older less–efficient designs. The  
chargepumpstillrequiresfourexternalcapacitors,  
but usesa four–phase voltage shiftingtechnique  
to attain symmetrical 10V power supplies.  
Figure 3a shows the waveform found on the  
positive side ofcapacitorC , andFigure 3b shows  
the negative side of cap2acitor C2. There is a  
free–running oscillator that controls the four  
phases of the voltage shifting. A description of  
each phase follows.  
All devices in this series feature low-power  
CMOS construction and Sipex's proprietary  
on-board charge pump circuitry to generate the  
+10V RS-232 voltage levels. The ability to  
use 0.1µF charge pump capacitors saves  
board space and reduces production costs.  
The devices in this series provide different  
driver/receiver combinations to match any  
application requirement.  
Phase 1  
VSS chargestorageDuringthisphaseofthe  
clock cycle, the positive side of capacitors C1  
and C2 are initially charged to +5V. Cl+ is then  
switched to ground and the charge in C1is  
transferred to C . Since C + is connected to  
+5V, the voltage2potential ac2ross capacitor C2 is  
now 10V.  
The SP211EH and SP213EH models feature a  
low–power shutdown mode, which reduces  
power supply drain to 1µA. The SP213EH  
includes a Wake-Up function which keeps two  
receivers active in the shutdown mode, unless  
disabled by the EN pin.  
Phase 2  
— VSS transfer — Phase two of the clock  
connects the negative terminal of C to the VSS  
storage capacitor and the positive ter2minal of C2  
to ground, and transfers the generated –l0V to  
C . Simultaneously, the positive side of capacitor  
C3 is switched to +5V and the negative side is  
co1nnected to ground.  
The family is available in 28–pin SO (wide) and  
SSOP (shrink) small outline packages. Devices  
can be specified for commercial (0°C to +70°C)  
and industrial/extended (–40°C to +85°C) oper-  
ating temperatures.  
Phase 3  
— VDD charge storage — The third phase of the  
clock is identical to the first phase — the charge  
transferred in C1 produces –5V in the negative  
terminal of C1, which is applied to the negative  
side of capacitor C . Since C2+ is at +5V, the  
voltage potential acr2oss C2 is l0V.  
THEORY OF OPERATION  
The SP207EH Series devices are made up of  
three basic circuit blocks — 1) transmitter/  
driver, 2) receiver and 3) the SIPEX–propri-  
etary charge pump. Each model within the  
Series incorporates variations of these circuits  
to achieve the desired configuration and  
performance.

The drivers are inverting transmitters, which  
accept either TTL or CMOS inputs and output the  
RS-232 signals with an inverted sense relative to  
the input logic levels. Typically, the RS-232  
outputvoltageswingis+9Vwithnoload,and+5V  
minimum with full load. The transmitter outputs  
are protected against infinite short–circuits to  
ground without degradation in reliability. The  
drivers of the SP211EH, and SP213EH can be  
tri–stated by using the SHUTDOWN function.  
Since both V+ and Vare separately generated  
from VCC; in a no–load condition V+ and Vwill  
be symmetrical. Older charge pump approaches  
that generate Vfrom V+ will show a decrease in  
the magnitude of Vcompared to V+ due to the  
inherent inefficiencies in the design.  
Inthepower-offstate,theoutputimpedancewill  
remaingreaterthan300ohms, againsatisfyingthe  
RS-232 specifications. Should the input of the  
driver be left open, an internal 400Kohm pullup  
resistor to VCC forces the input high, thus commit-  
ting the output to a low state. The slew rate of the  
transmitter output is internally limited to a maxi-  
mumof30V/µsinordertomeettheEIAstandards  
(EIA RS-232D 2.1.7, Paragraph 5). The transition  
of the loaded output from high to low also meets  
the monotonicity requirements of the standard.  
The clock rate for the charge pump typically  
operates at 15kHz. The external capacitors can  
be as low as 0.1µF with a 16V breakdown  
voltage rating.  
Transmitter/Driver  
The drivers of the SP207EH Series can maintain  
a typical data rate of 500Kbps. This superior  
RS-232 data transmission rate makes the  
SP207EH Series an ideal match for many

Receivers  
ThehighperformancereceiversoftheSP207EH  
Series can accept input signals at a typical data  
rate of 500Kbps. The receivers convert RS-232  
input signals to inverted TTL signals. The  
receivers convert RS-232 input signals to  
inverted TTL signals. Since the input is usually  
fromatransmissionlinewherelongcablelengths  
and system interference can degrade the signal,  
the inputs have a typical hysteresis margin of  
500mV. This ensures that the receiver is  
virtually immune to noisy transmission lines.  
Should an input be left unconnected, a 5kΩ  
pulldown resistor to ground will commit the  
output of the receiver to a high state.  
For complete shutdown to occur and the 10µA  
power drain to be realized, the following  
conditions must be met:  
SP211EH:  
• +5V must be applied to the SD pin  
• ENABLE must be either 0V, +5.0V or not  
connected  
• the transmitter inputs must be either +5.0V  
or not connected  
• VCC must be +5V  
• Receiver inputs must be >0V and <+5V  
SP213EH:  
• 0V must be applied to the SD pin  
SHUTDOWN MODE  
The SP211EH, and SP213EH all feature a  
control input which will disable the device and  
reduce the power supply current to less than  
10µA, making the parts ideal for battery–  
powered systems. In the “shutdown” mode the  
receiversandtransmitterswillbothbetri–stated.  
TheV+ outputofthechargepumpwilldischarge  
to VCC, and the Voutput will discharge to  
ground. Products with the Wake-Up function  
can enable or disable the receivers during  
shutdown.  
• ENABLE must be either 0V, +5.0V or not  
connected  
• the transmitter inputs must be either +5.0V  
or not connected  
• VCC must be +5V  
• Receiver inputs must be >0V and <+5V

The SP211EH and SP213EH all feature an

to be either tri–stated or enabled. This can be  
especially useful when the receiver is tied di-  
rectly to a microprocessor data bus. For the  
SP211EH, enable is active low; that is, 0V  
applied to the ENABLE pin will enable the  
receiver outputs. For the SP213EH, enable is

WAKEUP FUNCTION  
There are different methods of ESD testing  
applied:  
The SP213EH has a wake–up feature that keeps  
two receivers (R4 and R5) in an enabled state  
when the device is in the shutdown mode. With  
only the receivers active during shutdown, the  
devices draw 5–10µA of supply current.  
a) MIL-STD-883, Method 3015.7  
b) IEC1000-4-2 Air-Discharge  
c) IEC1000-4-2 Direct Contact  
The Human Body Model has been the generally  
acceptedESDtestingmethodforsemiconductors.  
This method is also specified in MIL-STD-883,  
Method 3015.7 for ESD testing. The premise of  
this ESD test is to simulate the human body’s  
potentialtostoreelectro-staticenergyanddischarge  
it to an integrated circuit. The simulation is  
performed by using a test model as shown  
in Figure 7. This method will test the IC’s  
capability to withstand an ESD transient during  
normal handling such as in manufacturing areas  
where the ICs tend to be handled frequently.  
A typical application of this function would be  
where a modem is interfaced to a computer in a  
power–down mode. The ring indicator signal  
from the modem could be passed through an  
active receiver in the SP213EH that is itself in  
the shutdown mode. The ring indicator signal  
would propagate through the SP213EH to the  
power management circuitry of the computer to  
power up the microprocessor and the SP213EH  
drivers.AfterthesupplyvoltagetotheSP213EH  
reaches +5.0V, the SHUTDOWN pin can be  
disabled, taking the SP213EH out of the  
shutdown mode.  
TheIEC-1000-4-2,formerlyIEC801-2,isgenerally  
used for testing ESD on equipment and systems.  
For system manufacturers, they must guarantee a  
certainamountofESDprotectionsincethesystem  
itself is exposed to the outside environment and  
human presence. The premise with IEC1000-4-2  
is that the system is required to withstand an  
amountofstaticelectricitywhenESDisappliedto  
points and surfaces of the equipment that are  
accessible to personnel during normal usage. The  
transceiver IC receives most of the ESD current  
when the ESD source is applied to the connector  
pins. The test circuit for IEC1000-4-2 is shown  
on Figure 8. There are two methods within  
IEC1000-4-2, the Air Discharge method and the  
Contact Discharge method.  
All receivers that are active during shutdown  
maintain 500mV (typical) of hysteresis.  
ESD TOLERANCE  
The SP207EH Family incorporates ruggedized  
ESD cells on all driver output and receiver input  
pins. The ESD structure is improved over our  
previous family for more rugged applications  
and environments sensitive to electro-static dis-  
chargesandassociatedtransients. Theimproved  
ESDtoleranceisatleast+15kVwithoutdamage  
nor latch-up.

Figure 8. ESD Test Circuit for IEC1000-4-2  
WiththeAirDischargeMethod,anESDvoltageis  
appliedtotheequipmentundertest(EUT)through  
air. This simulates an electrically charged person  
readytoconnectacableontotherearofthesystem  
only to find an unpleasant zap just before the  
person touches the back panel. The high energy  
potential on the person discharges through an  
arcingpathtotherearpanelofthesystembeforehe  
or she even touches the system. This energy,  
whether discharged directly or through air, is  
predominantly a function of the discharge current  
rather than the discharge voltage. Variables with  
an air discharge such as approach speed of the  
object carrying the ESD potential to the system  
and humidity will tend to change the discharge  
current. Forexample,therisetimeofthedischarge  
current varies with the approach speed.

Figure 9. ESD Test Waveform for IEC1000-4-2  
The circuit model in Figures 7 and 8 represent the  
typical ESD testing circuit used for all three  
methods. The CS is initially charged with the DC  
power supply when the first switch (SW1) is on.  
Now that the capacitor is charged, the second  
switch (SW2) is on while SW1 switches off. The  
voltage stored in the capacitor is then applied  
through RS, the current limiting resistor, onto the  
device under test (DUT). In ESD tests, the SW2  
switch is pulsed so that the device under test  
receives a duration of voltage.  
The Contact Discharge Method applies the ESD  
current directly to the EUT. This method was  
devised to reduce the unpredictability of the ESD  
arc. The discharge current rise time is constant  
since the energy is directly transferred without the  
air-gaparc. Insituationssuchashandheldsystems,  
the ESD charge can be directly discharged to the  
equipment from a person already holding the  
equipment. The current is transferred on to the  
keypad or the serial port of the equipment directly  
andthentravelsthroughthePCBandfinallytotheIC.

For the Human Body Model, the current limiting  
resistor (RS) and the source capacitor (CS) are  
1.5kan100pF, respectively. ForIEC-1000-4-2,  
the current limiting resistor (RS) and the source  
capacitor (CS) are 330an 150pF, respectively.  
EIA STANDARDS  
The Electronic Industry Association (EIA)  
developed several standards of data transmission  
which are revised and updated in order to meet  
the requirements of the industry. In data  
processing, there are two basic means of  
communicatingbetweensystemsandcomponents.  
The RS-232 standard was first introduced in  
1962 and, since that time, has become an  
industry standard.  
The higher C value and lower RS value in the  
IEC1000-4-2 Smodel are more stringent than the  
HumanBodyModel. Thelargerstoragecapacitor  
injectsahighervoltagetothetestpointwhenSW2  
is switched on. The lower current limiting resistor  
increases the current charge onto the test point.  
The RS-232 is a relatively slow data exchange  
protocol, with a maximum baud rate of only  
20kbps, which can be transmitted over a  
maximum copper wire cable length of 50 feet.  
The SP207EHthroughSP213EHSeriesofdata  
communications interface products have been  
designed to meet both the EIA protocol  
standards, and the needs of the industry.
