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.

²The DB package is only available left-ended taped (order AM26C31IDBLE or AM26C31CDBLE).

²Stresses beyond those listed under ªabsolute maximum ratingsº may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under ªrecommended operating conditionsº is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
