DS26LS31C/DS26LS31M

Quad High Speed Differential Line Driver

General Description

The DS26LS31 is a quad differential line driver designed for

digital

data

transmission

over

balanced

lines.

The

DS26LS31 meets all the requirements of EIA Standard RS-

422 and Federal Standard 1020. It is designed to provide

unipolar differential drive to twisted-pair or parallel-wire

transmission lines.

The circuit provides an enable and disable function common

outputs and logically ANDed complementary outputs. The

inputs are all LS compatible and are all one unit load.
