DESCRIPTION

The LM161/LM361 is a very high speed differential

input, complementary TTL output voltage comparator

with improved characteristics over the SE529/NE529

for which it is a pin-for-pin replacement. The device

has been optimized for greater speed performance

and lower input offset voltage. Typically delay varies only 3 ns for over-drive variations of 5 mV to 500 mV.

It may be operated from op amp supplies (±15V).

Complementary outputs having maximum skew are

provided. Applications involve high speed analog to

digital converters and zero-crossing detectors in disk

file systems.
