DESCRIPTION

The ST485A is a low power, high speed

transceiver

for

RS-485

and

RS-422

communications. The device contains one driver

and one receiver in half duplex configuration. The

ST485A draws 3mA (typ.) of supply current when

Package

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 place the driver

outputs into a high-impedance state. The receiver

input has a fail-safe feature that guarantees a

logic high output if both inputs are open circuit.

The ST485A is designed for bi-directional data

communications or multipoint bus transmission

lines.
