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 V to as high as ±6 V.

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 indus-

trial (–40°C to +125°C) temperature range. Both are available in

narrow SO-16 surface-mount packages and 16-lead TSSOP.
