Driver is short-circuit current limited and is

protected against excessive power dissipation by

thermal shutdown circuitry that placed the driver

outputs into a high-impedance state. .

DESCRIPTION

The ST485 is designed for bi-directional data

communications on multipoint bus transmission

line (half-duplex applciations).

The ST485 is al low power transceiver for RS-485

and RS-422 communication. Each part contains

one driver and one receiver.

The ST485 is available in three temperature

range: commercial (0°C to 70°C), industrial (-40°C

to 850°C) and automotive (-55°C to 125°C)

This transceiver draw 300µA (typ.) of supply

current when unloaded or fully loaded with

disabled drivers.
