QUAD EIA–485
LINE RECEIVER WITH
THREE–STATE OUTPUTS
The Motorola SN75175 is a monolithic quad differential line receiver with
three–state outputs. It is designed specifically to meet the requirements of
EIA–485, EIA–422A/23A Standards and CCITT recommendations.
The device is optimized for balanced multipoint bus transmission at rates
up to 10 megabits per second. It also 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. The SN75175 is
designed for optimum performance when used with the SN75172 or
SN75174 quad differential line drivers.
