LM160/LM360
High Speed Differential Comparator
General Description
The LM160/LM360 is a very high speed differential input,
complementary TTL output voltage comparator with im-
proved characteristics over the µA760/µA760C, for which it
is a pin-for-pin replacement. The device has been optimized
for greater speed, input impedance and fan-out, and lower
input offset voltage. Typically delay varies only 3 ns for
overdrive variations of 5 mV to 400 mV.
Complementary outputs having minimum skew are provided.
Applications involve high speed analog to digital convertors
and zero-crossing detectors in disk file systems.
Features
nGuaranteed high speed: 20 ns max
nTight delay matching on both outputs
nComplementary TTL outputs
nHigh input impedance
nLow speed variation with overdrive variation
nFan-out of 4
nLow input offset voltage
nSeries 74 TTL compatible
