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.

Stresses beyond those listed under “absolute maximum ratings” 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 “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: All voltage values, except differential output voltage (VOD), are with respect to the network ground terminal.
