latchup. These parts contain one driver and one

receiver.

This transceiver draws 300µA (typ.) of supply

current when unloaded or fully loaded with

disabled drivers.

ESD PROTECTION:

±15KV (H.B.M.)

±8KV (IEC-1000-4-2 CONTACT

THE BUS

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 places the driver

outputs into a high-impedance state.

The ST485E is designed for bi-directional data

communications on multipoint bus transmission

line (half-duplex applciations).

DESCRIPTION

The ST485E is al low power transceiver for

RS-485 and RS-422 communication. Each driver

output and receiver input is protected against

±15KV electrostatic discharge (H.B.M.) ±8KV

(IEC-1000-4-2 contact discharge) shocks, without
