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.) (ESD)

shocks, without latcup. These parts contain one

driver

and

one

receiver

in

half

duplex

configuration.

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 place the driver

outputs into a high-impedance state.

The ST485E is designed for bi-directional data

communications on multipoint bus transmission

line (half-duplex applications).
