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.
