description

The AM26LV31 is a BiCMOS quadruple differential line driver with 3-state outputs. It is designed to be similar

to TIA/EIA-422-B and ITU Recommendation V.11 drivers with reduced supply-voltage range.

The device is optimized for balanced-bus transmission at switching rates up to 32 MHz. The outputs have very

high current capability for driving balanced lines such as twisted-pair transmission lines and provide a high

impedance in the power-off condition. The enable function is common to all four drivers and offers the choice

of active-high or active-low enable inputs. The AM26LV31 is designed using Texas Instruments (TI

™)

proprietary LinIMPACT-C60

™ technology, facilitating ultra-low power consumption without sacrificing speed.

This device offers optimum performance when used with the AM26LV32 quadruple line receivers.

The AM26LV31C is characterized for operation from 0

°C to 70°C.
