AM26C31C General Description
The AM26C31C, AM26C31I, and AM26C31M are four complementary-output line drivers 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 function is common to all four drivers and offers the choice of an active-high or active-low enable input. BiCMOS circuitry reduces power consumption without sacrificing speed.
The AM26C31C is characterized for operation from 0°C to 70°C, the AM26C31I is characterized for operation from 40°C to 85°C, and the AM26C31M is characterized for operation from 55°C to 125°C.
