LM160/LM360

High Speed Differential Comparator

General Description

The LM160/LM360 is a very high speed differential input,

complementary TTL output voltage comparator with im-

proved characteristics over the µA760/µA760C, for which it

is a pin-for-pin replacement. The device has been optimized

for greater speed, input impedance and fan-out, and lower

input offset voltage. Typically delay varies only 3 ns for over-

drive variations of 5 mV to 400 mV.

Complementary outputs having minimum skew are provided.

Applications involve high speed analog to digital convertors

and zero-crossing detectors in disk file systems.
