DS75114 Dual Differential Line Drivers
General Description
The DS75114 dual differential line driver is designed to pro-
vide differential output signals with 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 pull-
up terminals YP and ZP available on adjacent package
pins Since the output stages provide TTL compatible output
levels these devices may also be used as TTL expanders
or phase splitters
