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.
