SN75ALS191 - Dual Differential Line Driver

General 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.

Key Features

  • Meets or exceeds the requirements of ANSI standard EIA/TIA-422-B and ITU recommendation V.11.
  • Designed to operate at 20 Mbaud or higher.
  • TTL-and CMOS-input compatibility.
  • Single 5V supply operation.
  • Output short-circuit protection.
  • Improved replacement for the μA9638 2.
