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.
The SN55114 is characterized for operation over the full military temperature range of 55
C to 125
C. The
SN75114 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.

All parameters, with the exception of off-state open-collector output current, are measured with the active pullup connected to the sink output.
For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions.
All typical values are at TA = 25
C and VCC = 5 V, with the exception of ICC at 7 V.
Only one output should be shorted at a time, and duration of the short circuit should not exceed one second.
