DESCRIPTION
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 300µA (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 placed the driver outputs into a high-impedance state. . The ST485 is designed for bi-directional data communications on multipoint bus transmission line (half-duplex applciations).
