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.

NOTES: 1. All voltage values are with respect to the network ground terminal.
