Overview
LM161/LM261/LM361 High Speed Differential Comparators May 1999 LM161/LM261/LM361 High Speed Differential Comparators General Description The LM161/LM261/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 n n n n n n n n 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 Connection Diagrams Dual-In-Line Package Metal Can Package DS005708-3 Order Number LM161H/883 (Note 1), or LM361H See NS Package Number H10C DS005708-2 Top View Order Number LM161J LM361M or LM361N See NS Package Number M14A or N14A Note 1: Also available per SMD #5962-8757203 © 1999 National Semiconductor Corporation DS005708 www.
