DESCRIPTION
The SP206, SP207, SP208 and SP2ꢀꢀ are multi-channel RS-232 line transceivers in a variety of
configurations to fit most communication needs. All models in this series feature low-power CMOS
construction and Exar Patented (5,306,954) on-board charge pump circuitry to generate the +/-ꢀ0V
RS-232 voltage levels, using 0.ꢀµF charge pump capacitors to save board space and reduce circuit
cost. The SP206 and SP2ꢀꢀ models feature a low-power shutdown mode which reduces power sup-
ply drain to ꢀ µA.

DESCRIPTION
PHASE 2
FEATURES
Vss transfer: Phase two of the clock connects
the negative terminal of C2 to the Vss stor-
age capacitor and the positive terminal of C2
to ground, and transfers the generated -ꢀ0V to
C3. Simultaneously, the positive side of capaci-
tor Cꢀ is switched to +5V and the negative side
is connected to ground.
The SP206/207/208/2ꢀꢀ multi-channel RS-232
line transceivers provide a variety of configu-
rations to fit most communication needs, es-
pecially those applications where +/-ꢀ2V is not
available. All models in this series feature low-
power CMOS construction and Exar's proprie-
tary on-board charge pump circuitry to generate
the +/-ꢀ0V RS-232 voltage levels. The ability to
use 0.ꢀµF charge pump capacitors saves board
space and reduces circuit cost. Different mod-
els within the series provide different driver/re-
ceiver combinations to match any application
requirement.
PHASE 3
Vdd charge storage: The third phase of the
clock is identical to the first phase. The charge
transferred in Cꢀ produces -5V in the negative
terminal of Cꢀ, which is applied to the negative
side of C2. Since C2+ is at +5V, the voltage po-
tential across C2 is ꢀ0V.
The SP206 and SP2ꢀꢀ models feature a low-
power shutdown mode that reduces power sup-
ply drain to ꢀµA.
PHASE 4
Vdd transfer: The fourth phase of the clock con-
nects the negative terminal of C2 to ground,
and transfers the generated ꢀ0V across C2 to
C4, the Vdd storage capacitor. Again, simulta-
neously with this, the positive side of capaci-
tor Cꢀ is switched to +5V and the negative side
is connected to ground, and the cycle begins
again.
The models in this series are available in 24-pin
and 28-pin SO (wide) and SSOP (shrink) small
outline packages. Devices can be specified for
commercial (0ºC to +70ºC) or industrial/extend-
ed (-40ºC to +85ºC) operating temperatures.
THEORY OF OPERATION
Since both V+ and V- are separately generated
from Vcc; in a no-load condition V+ and V- will
be symmetrical. Older charge pump approach-
es that generate V- from V+ will show a de-
crease in magnitude of V- compared to V+ due
to the inherent inefficiencies in the design.
CHARgE PUMP
The charge pump is an Exar patented design
and uses a unique approach compared to older
less-efficient designs. The charge pump still
requires four external capacitors, but uses a
four phase voltage shifting technique to attain
symmetrical +/-ꢀ0V power supplies. Figure ꢀa
shows the waveform found on the positive side
of capacitor C2 and Figure 3b shows the nega-
tive side of capacitor C2. There is a free-run-
ning oscillator that controls the four phases of
the voltage shifting. A description of each phase
follows:
The clock rate for the charge pump typically op-
erates at greater than ꢀ5kHz allowing the pump
to run efficiently with small 0.1uF capacitors
with a ꢀ6V breakdown voltage rating.
The SP206/207/208/2ꢀꢀ devices are made up
of three basic circuit blocks - ꢀ) transmitter/
driver, 2) receiver and 3) charge pump. Each
model within the series incorporates variations
of these circuit to achieve the desired configu-
ration and performance.
PHASE 1
Vss charge storage - During this phase of the
clock cycle, the positive side of capacitors Cꢀ
and C2 are initially charged to +5V. Cꢀ+ is then
switched to ground and the charge in Cꢀ- is
transferred to C2-. Since C2+ is connected to
+5V, the voltage potential across capacitor C2
is now ꢀ0V.

DESCRIPTION
RECEIVERS
The receivers convert RS-232 input signals to
inverted TTL signals. Since the input is usu-
ally from a transmission line where long cable
length and system interference can degrade
the signal, the inputs have a typical hysteresis
margin of 500mV. This ensures that the re-
ceiver is virtually immune to noisy transmission
lines. Should an input be left unconnected, an
internal 5kohm pull-down resistor to ground will
commit the output of the receiver to a HIGH
state.

SHUTDOWN MODE
Figure ꢀ. Charge Pump Waveforms
The SP206 and SP2ꢀꢀ feature a control input
(SD) which will disable the device and reduce
the power supply current to less than ꢀ0µA,
making the parts ideal for battery-powered sys-
tems. In the "shutdown" mode the receivers
and transmitters will both be tri-stated. The V+
output of the charge pump will discharge to Vcc
and the V- output will discharge to ground.
TRANSMITTER/DRIVER
The drivers are inverting transmitters, which ac-
cept either TTL or CMOS inputs and output the
RS-232 output signals with an inverted sense
relative to the input logic levels. Typically, the
RS-232 output voltage swing is +/-9V with no
load, and +/-5V minimum with full load. The
transmitter outputs are protected against infi-
nite short-circuits to ground without degrada-
tion in reliability. The drivers of the SP206 and
SP2ꢀꢀ can be tri-stated by using the SHUT-
DOWN function.
ENAbꢀE (EN)
The SP206 and SP2ꢀꢀ feature an enable input
which allows the receiver outputs to be either
tri-stated or enabled. This can be especially
useful when the receiver is tied directly to a
microprocessor data bus. The enable pin is
active high.
In the "power off" state, the output impedance
will remain greater than 300 Ohms, again satis-
fyingtheRS-232specifications. Shouldtheinput
of the driver be left open, an internal 400kOhm
pull-up resistor to Vcc forces the input high, thus
committing the output to a low state. The slew
rate of the transmitter output is internally limited
to a maximum of 30V/µs in order to meet he EIA
standards (EIA RS-232D 2,ꢀ,7, Paragraph 5).
The transition of the loaded output from high to
low also meets the monotonicity requirements
of the standard.

EIA STANDARDS
The Electronic Industry Association (EIA)
+/-10ꢁV ESD PROTECTION
The SP206/207/208/2ꢀꢀ are equipped with
Exar proprietary ESD protection circuitry on
all RS-232 inputs and outputs. This series
has been characterized using MIL-STD-883C
Method 30ꢀ5.7 Human Body Model. Each
device in the family can withstand up to +/-
ꢀ0kV of static discharge on all RS-232 inputs
and outputs. All other pins of each device will
maintain ≥ +/-2kV of ESD protection.
developed several standards of data transmis-
sion which are revised and updated in order to
meet the requirements of the industry. In data
processing, there are two basic means of com-
municating between systems and components.
The RS-232 standard was first introduced in
ꢀ962 and, since that time, has become an
industry standard.
The RS-232 is a relatively slow data exchange
protocol, with a maximum baud rate of only
20kbaud, which can be transmitted over a
maximum copper wire cable length of 50 feet.
The SP206 through SP2ꢀꢀ series of data com-
munications interface products have been de-
signed to meet both the EIA protocol standards
, and the needs of the industry.
