DESCRIPTION/ORDERING INFORMATION
The AM26LS31 is a quadruple complementary-output
line driver designed to meet the requirements of ANSI
FK PACKAGE
(TOP VIEW)
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 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.
