Recommendation V.11

description

The SN75ALS191 is a dual, high-speed, differential line driver designed to meet ANSI Standard EIA/TIA-422-B

and ITU Recommendation V.11. The inputs are TTL- and CMOS-compatible and have input clamp diodes.

Schottky-diode-clamped transistors minimize propagation delay time. This device operates from a single 5-V

power supply and is supplied in eight-pin packages.

The SN75ALS191 is characterized for operation from 0

°C to 70°C.
