LM161/LM361 High Speed Differential Comparators
Check for Samples: LM161, LM361
•2 Independent strobes
• Ensured 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
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
