DS26LS31C/DS26LS31M
Quad High Speed Differential Line Driver
General Description
The DS26LS31 is a quad differential line driver designed for
digital
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.
