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.

+/-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.
