DS26LS31MQML

Quad High Speed Differential Line Driver

General Description

The DS26LS31MQML is a quad differential line driver de-

signed for digital data transmission over balanced lines. The

DS26LS31MQML meets all the requirements of EIA Stan-

dard 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

to all four drivers. The DS26LS31MQML features TRI-

puts. The inputs are all LS compatible and are all one unit

load.

The DS26LS31 features a power up/down protection circuit

which keeps the output in a high impedance stat (TRI-

STATE) during power up or down preventing erroneous

glitches on the transmission lines.
