FEATURES 65 ns Propagation Delay Single-Supply Operation Compatible with 3 V and 5 V Logic Separate Input and Output Sections Low Power Wide Input Range: +3.9 V APPLICATIONS Battery-Operated Instrumentation Line Receivers Level Translators Read Channel Detection

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 to as high 6 V. The output can be supplied with either 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 industrial to +125�C) temperature range. Both are available in narrow SO-16 surface-mount packages and 16-lead TSSOP.
