The DS75114 dual differential line driver is designed to provide 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 pullup 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
