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.
