a FEATURES 23 ns or 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: –5 V to +3.9 V APPLICATIONS Battery-Operated Instrumentation Line Receivers Level Translators Read Channel Detection 23 ns and 65 ns Low Voltage Comparators CMP401/CMP402 FUNCTIONAL BLOCK DIAGRAM VANALOG+ = 0V OR 5V VDIGITAL = 3V OR 5V IN+ OUTPUT IN– VANALOG– = +0V OR –5V NOTE: (VANALOG+ ) – (VANALOG–) 3V GENERAL DESCRIPTION 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 V to as high as ± 6 V. 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 industrial (–40°C to +125°C) temperature range. Both are available in narrow SO-16 surface-mount packages and 16-lead TSSOP. 50mV 100 90 2v 10 0% 10nS CMP401: 20 MHz Noninverting Switching, VIN = ± 100 mV R EV.

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. WARNING! ESD SENSITIVE DEVICE –4– REV.
