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.

The AM26C31C is characterized for operation from 0°C to 70°C, the AM26C31I is characterized for operation

from –40°C to 85°C, the AM26C31Q is characterized for operation over the automotive temperature range

of –40°C to 125°C, and the AM26C31M is characterized for operation over the full military temperature range

of –55°C to 125°C.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
