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 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 receiver input has a fail safe feature that guarantees a logic-high output if the input is open circuit. The ST75C176 is designed for bi-directional data communications on multipoint bus transmission line (half-duplex applciations).
