Separate supplies 100 90 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. 10 The CMP401 and CMP402 are specified over the extended indus- 0% trial (40C to +125C) temperature range. Both are available in 10nS narrow 16-lead SOIC surface-mount packages and 16-lead TSSOP. CMP401: 20 MHz Noninverting Switching, V = 100 mV IN REV.
