description
The SN55114 and SN75114 dual differential line
drivers are designed to provide differential output
signals with the high-current capability for driving
balanced lines, such as twisted pair, at normal line
impedances without high power dissipation. The
output stages are similar to TTL totem-pole
outputs, but with the sink outputs, YS and ZS, and
the corresponding active pullup terminals, YP and
ZP , available on adjacent package pins. Since the
output stages provide TTL-compatible output
levels, these devices can also be used as TTL
expanders or phase splitters.

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.
