3 Description
The AM26C31 device 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 AM26C31C device is characterized for operation from 0°C to 70°C, the AM26C31I device is characterized for operation from –40°C to 85°C, the AM26C31Q device is characterized for operation over the automotive temperature range of –40°C to 125°C, and the AM26C31M device is characterized for operation over the full military temperature range of –55°C to 125°C.
