SN75173

Quad EIA-485 Line Receivers The Motorola SN75173/175 are monolithic quad differential line receivers with three–state outputs. They are designed specifically to meet the requirements of EIA–485, EIA–422A/23A Standards and CCITT recommendations. The devices are optimized for balanced multipoint bus transmission at rates up to 10 megabits per second. They also feature high input impedance, input hysteresis for increased noise immunity, and input sensitivity of ± 200 mV over a common mode input voltage range of – 12 V to 12 V. The SN75173/175 are designed for optimum performance when used with the SN75172 or SN75174 quad differential line drivers.
