DESCRIPTION/ORDERING INFORMATION
The AM26C31 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.

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.
All voltage values, except differential voltages, are with respect to the network ground terminal.
Maximum power dissipation is a function of T
J(max
),
θ
JA
, and T
A
. The maximum allowable power dissipation at any allowable ambient
temperature is P
D
= (T

. Operating at the absolute maximum T

of 150°C can affect reliability.
The package thermal impedance is calculated in accordance with JESD 51-7.
