MILITARY DATA SHEET Original Creation Date: 01/24/96 Last Update Date: 11/15/96 Last Major Revision Date: 01/24/96 MNDS26LS31M-X REV 0A0 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.
