LM160QML
High Speed Differential Comparator
General Description
Features
The LM160 is a very high speed differential input, complementary TTL output voltage comparator with improved characteristics over the μA760/μA760C, for which it is a pin-forpin replacement. The device has been optimized for greater
speed, input impedance and fan-out, and lower input offset
voltage. Typically delay varies only 3nS for overdrive variations of 5mV to 400mV.
Complementary outputs having minimum skew are provided.
Applications involve high speed analog to digital convertors
and zero-crossing detectors in disk file systems.

Note 2: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed
specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test
conditions.
