Description

The SN75447P is a quad EIA–485 line receiver designed to meet the requirements of EIA–485, EIA–422A/23A Standards and CCITT recommendations. It is optimized for balanced multipoint bus transmission at rates up to 10 megabits per second. The device features 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. It is designed for optimum performance when used with the SN75172 or SN75174 quad differential line drivers.
