ST485B - Low power RS-485/RS-422 transceiver

The ST485 is al low power transceiver for RS-485 and RS-422 communication.

Each part contains one driver and one receiver.

This transceiver draw 300 µA (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
