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
