DS96173/DS96175 RS-485/RS-422 Quad Differential Line Receivers June 1998 DS96173/DS96175 RS-485/RS-422 Quad Differential Line Receivers General Description The DS96173 and DS96175 are high speed quad differential line receivers designed to meet EIA Standard RS-485. The devices have TRI-STATE ® outputs and are optimized for balanced multipoint data bus transmission at rates up to 10 Mbps. The receivers feature high input impedance, input hysteresis for increased noise immunity, and input sensitivity of 200 mV over a common mode input voltage range of −7V to +12V. The receivers are therefore suitable for multipoint applications in noisy environments. The DS96173 features an active high and active low Enable, common to all four receivers. The DS96175 features separate active high Enables for each receiver pair. Compatible RS-485 drivers, transceivers, and repeaters are also offered to provide optimum bus performance. The respective device types are DS96172, DS96174, DS96176 and DS96177.
