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
  • 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.
