description/ordering information

The AM26LS31 is a quadruple
complementary-output line driver designed to
meet the requirements of ANSI TIA/EIA-422-B
and ITU (formerly CCITT) Recommendation V .1 1.
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 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.
