DS26LS31MQML DS26LS31MQML Quad High Speed Differential Line Driver Literature Number: SNOSAM5A DS26LS31MQML Quad High Speed Differential Line Driver General Description Features The DS26LS31MQML is a quad differential line driver designed for digital data transmission over balanced lines. The DS26LS31MQML 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 parallelwire transmission lines. n Operation from single 5V supply n Outputs won’t load line when VCC = 0V n Four line drivers in one package for maximum package density n Output short-circuit protection n Complementary outputs n Meets the requirements of EIA Standard RS-422 n Pin compatible with AM26LS31 n Glitch free power up/down The circuit provides an enable and disable function common to all four drivers. The DS26LS31MQML features TRISTATE ® 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 stat (TRISTATE) during power up or down preventing erroneous glitches on the transmission lines.
