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.

Features

Independent strobes
Guaranteed high speed: 20 ns max
Tight delay matching on both outputs
Complementary TTL outputs
Operates from op amp supplies: ±15V
Low speed variation with overdrive variation
Low input offset voltage
Versatile supply voltage range
