3 Description

The AM26LS31 family of devices is a quadruple

complementary-output line driver designed to meet

the requirements of ANSI TIA/EIA-422-B and ITU

(formerly CCITT) Recommendation V.11. The 3-state

outputs have high-current capability for driving

balanced lines such as twisted-pair or parallel-wire

transmission lines, and they are in the highimpedance

state in the power-off condition. The

enable function is common to all four drivers and

offers the choice of an active-high or active-low

enable (G, G) input. Low-power Schottky circuitry

reduces power consumption without sacrificing

speed.
