MILITARY DATA SHEET

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 to all four drivers. The

DS26LS31 features TRI-STATE outputs and logically ANDed complementary outputs. 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 state (TRI-STATE) during power up or down preventing erroneous glitches on the

transmission lines.
