3 Description

The SN75158 is a dual differential line driver designed

to satisfy the requirements set by the ANSI EIA/

TIA-422-B and ITU V.11 interface specifications. The

outputs provide signals with high-current capability for

driving balanced lines, such as twisted pair, at normal

line impedance without high power dissipation. The

output stages are TTL totem-pole outputs, providing a

high-impedance state in the power-off condition.

The SN75158 is characterized for operation from 0°C

to 70°C.
