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.
