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.
