Triple RS232 Driver/Receiver

with Shutdown

FEATURES

DESCRIPTION

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

includes 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. On-chip ESD

protection eliminates the need for external protection

devices.

■

On-Chip ESD Protection:

±15kV Human Body Model

±15kV IEC-1000-4-2 Air Gap Test**

±8kV IEC-1000-4-2 Contact Test

■

125kBd Operation with 3kΩ/2500pF Load

■

250kBd Operation with 3kΩ/1000pF Load

■

Operates from ±5V to ±15V Supplies

■

Fully Protected Against Overload

■

Outputs Can Be Driven ±30V Without Damage

■

Three-State Outputs; Outputs Open When Off

■

Bipolar Circuit—No Latchup

±30V Input Range

Triple Driver/Receiver

■

A bias pin allows one receiver to be kept on while the rest

of the part is shut down.

■

No Supply Current in Shutdown

The LT1039A is also available in the 16-pin version,

without shutdown or bias pin functions.

■

30kΩ Input Impedance

■

Meets All RS232 Specifications

For applications requiring operation from a single 5V

supply, see the LT1180A/LT1181A and LT1130A data

sheets.

■

16-Pin Version—Pin Compatible with MC145406

Available in SO Package
