SN75DP129 - Brand New Texas Instruments Interface - Specialized
-
Description
The SN75DP129 is a quad EIA–485 line receiver, designed specifically 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 SN75DP129 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.
