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 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).

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
