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
to all four drivers. The DS26LS31 featuresTRI-STATE
®
out-
puts and logically ANDed complementary outputs. The in-
puts are all LS compatible and are all one unit load.
Features
n Output skew—2.0 ns typical
n Input to output delay—10 ns typical
n Operation from single 5V supply
n Outputs won’t load line when V
CC
=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 Available in military and commercial temperature range
