GENERAL DESCRIPTION
The CMP401 and CMP402 are 23 ns and 65 ns quad comparators 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 propagation 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.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the CMP401/CMP402 features proprietary ESD protection circuitry, permanent damage
may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
