3 Description

The AM26LS31CN-E 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 are in the high-impedance

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.
