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 V to as high as ±6V.
The output can be supplied with either 3 V or 5 V 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
narrow SO-16 surface-mount packages and 16-lead TSSOP.

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.
