GENERAL DESCRIPTION
The LM161 is a very high speed differential input,
complementary TTL output voltage comparator with improved
characteristics over similar devices 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.

*Stresses greater than those listed under "Absolute Maximum
Ratings" may cause permanent damage to the device. This is
a stress rating only and functional operation of the device at
these or any other conditions above those indicated in the
operation section of this specification is not implied. Exposure
to absolute maximum rating conditions for extended periods
may affect reliability.
