description/ordering information
The AM26C31 is a differential line driver with
complementary outputs, designed to meet the
requirements of TIA/EIA-422-B and ITU (formerly
CCITT). The 3-state outputs have high-current
capability for driving balanced lines, such as
twisted-pair or parallel-wire transmission lines,
and they provide the high-impedance state in the
power-off condition. The enable functions are
common to all four drivers and offer the choice of
an active-high (G) or active-low (G) enable input.
BiCMOS circuitry reduces power consumption
without sacrificing speed.
