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.
