Description

The ST490A is a low power transceiver for RS-

485 and RS-422 communications. The device

contains one driver and one receiver in full duplex

configuration. The ST490A draws 5mA (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 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.
