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 300mA (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). The ST485 is available in three temperature range: commercial (0C to 70C), industrial (- 40C to 850C) and automotive (-55C to 125C) By STMicroelectronics
