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 ±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 indus-
trial (–40°C to +125°C) temperature range. Both are available in
narrow 16-lead SOIC surface-mount packages and 16-lead TSSOP.
