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 volt-
age. 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 pro-
vided. Applications involve high speed analog to digital con-
verters and zero-crossing detectors in disk file systems.
