GENERAL DESCRIPTION
The CMP401 and CMP402 are 23 ns and 65 ns quad comp-
arators with separate input and output supplies. Separate supplies
enable the input stage to be operated from +3 volts to as high as
±6 volts. The output can be supplied with either +3 volts or
+5 volts as determined by the interface logic or available supplies.
Independent input and output supplies combined with fast prop-
agation make the CMP401 and CMP402 excellent choices for
interfacing to portable instrumentation.
The CMP401 and CMP402 are specified over the extended
industrial (–40°C to +125°C) temperature range. Both are
available in 16-pin plastic DIP or narrow SO-16 surface mount
packages. Consult factory for 16-lead TSSOP availability.
