MITSUBISHI MITSUBISHI 〈DIGITAL 〈DIGITAL ASSP ASSP 〉 〉 M75176P, M75176P, M75177P M75177P M75178P, M75178P, M75179P M75179P RS-485 TRANSCEIVER RS-485 TRANSCEIVER DESCRIPTION Each of the M75176 to M75179 is a semiconductor IC with a built-in differential driver and a built-in differential receiver both of which meet the EIA standards RS-422A and RS-485. FEATURES Common 5V single power supply With output control input (except M75179P) Driver 54Ω terminal resistor connectable between outputs. High output impedance at power-OFF time Built-in output current limit circuit Receiver High input sensitivity (±200mV max.) Hysteresis input (50mV typ.) High input impedance (12kΩ min.) “H” emitted when input is open (failsafe function) APPLICATION High-speed data transmission interface for digital equipment DESCRIPTION OF FUNCTION The M75176P to M75179P are line interface ICs which meet EIA standards RS-422A and RS-485, and are suitable for long-distance, high-speed data transmission. The M75176P is designed to connect the driver circuit output and the receiver input to each other internally, and serves as a line transceiver. The M75177P/M75178P is designed to connect the receiver circuit output and the driver circuit input internally, and serves as a line repeater. The M75177P and M75178P enter the output enabled state with active “H” and active “L”, respectively. The M75179P is equipped with a built-in differential driver and a built-in differential receiver.
