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.

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. –4– 16 OUT C OUT D DIG GND V– ANA –IN D +IN D –IN C +IN C CMP401/ 402 TOP VIEW (Not to Scale) 8 9 WARNING!
