DESCRIPTION

The ST75C176 is al low power transceiver for

RS-485 and RS-422 communication. Each part

contains one driver and one receiver.

This transceiver draw 300

µA (typ.) of supply

current when unloaded or fully loaded with

disabled drivers.

It operates from a single 5V supply.

Driver is short-circuit current limited and is

protected against excessive power dissipation by

thermal shutdown circuitry that placed the driver

outputs into a high-impedance state. The receiver

input has a fail safe feature that guarantees a

logic-high output if the input is open circuit.

The ST75C176 is designed for bi-directional data

communications on multipoint bus transmission

line (half-duplex applciations).
