RS232 Driver/Receiver

with Shutdown

FEATURES

DESCRIPTIO

The LT^®1039 is a triple RS232 driver/receiver that in-

cludes shutdown. Each receiver will accept up to ±30V

input and can drive either TTL or CMOS logic. The RS232

driversacceptTTLlogicinputsandoutputRS232voltage

levels. The outputs are fully protected against overload

and can be shorted to ground or up to ±30V without

damage to the drivers. Additionally, when the system is

shut down or power is off, the outputs are in a high

impedance state allowing data line sharing. Bipolar cir-

cuitry makes this driver/receiver exceptionally rugged

against overloads and immune to latchup.

15kV ESD: LT1039A

The LT1039 is also available in the 16-pin version,

without shutdown or BIAS pin functions.

APPLICATIO S

For applications requiring operation from a single 5V

supply, see the LT1080/LT1081, LT1180A/LT1181A and

LT1130A data sheets. For applications requiring 15kV

ESD, see the LT1039A.
