Overview
The AM26C31ID is a differential line driver with complementary outputs, designed and manufactured by Texas Instruments. This device is specifically engineered to meet the requirements of TIA/EIA-422-B and ITU (formerly CCITT) standards. It features 3-state outputs with high-current capability, making it suitable for driving balanced lines such as twisted-pair or parallel-wire transmission lines. The AM26C31ID also provides a high-impedance state in the power-off condition and includes enable functions that are common to all four drivers, offering the choice of an active-high or active-low enable input. BiCMOS circuitry is used to reduce power consumption without compromising speed.
