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.
