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 complementary 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.
