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.
The AM26C31 is characterized for operation over extended temperature range of –55°C to 125°C.
