ST490AB

Low power high speed

RS-485/RS-422 transceiver

Features

■ Low supply current: 5 mA max

■ -7 V to 12 V common mode input voltage range

■ 70 mV typical input hysteresis

■ Designed for 25 Mbps operation

■ Operate from a single 5 V supply

■ ±4 kV ESD protection

■ Current limiting and thermal shutdown for

driver overload protection

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 5 mA (typ.) of

supply current when unloaded or fully loaded with

disabled drivers. It operates from a single 5 V

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.
