LM161/LM361
High Speed Differential Comparators
General Description
Features
n Independent strobes
The LM161/LM361 is a very high speed differential input,
complementary TTL output voltage comparator with im-
proved 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).
n Guaranteed high speed: 20 ns max
n Tight delay matching on both outputs
n Complementary TTL outputs
n Operates from op amp supplies:
n Low speed variation with overdrive variation
n Low input offset voltage
15V
n Versatile supply voltage range
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.
