CMP401:  23 ns Low Voltage Comparator

Product Details

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.
