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.

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.
