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.
