description
The AM26LS31C 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 provide
a 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.
The AM26LS31C is characterized for operation from 0°C to 70°C.
