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.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: All voltage values, except differential output voltage VOD, are with respect to network ground terminal. VOD is at the Y output with respect
to the Z output.
