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 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.
