SN75ALS191 双路差动线路驱动器

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 minimizes propagation delay time. This device operates from a single 5-V power supply and is supplied in 8-pin packages.

The SN75ALS191 is characterized for operation from 0°C to 70°C
