APPLICATIONS

Battery-Operated Instrumentation Line Receivers Level Translators Read Channel Detection 10 10nS 50mV 100 CMP401: 20 MHz Noninverting Switching, VIN = ±100 mV GENERAL DESCRIPTION The CMP401 and CMP402 are 23 ns and 65 ns quad comp- arators with separate input and output supplies. Separate supplies 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. The CMP401 and CMP402 are specified over the extended indus- trial (–40°C to +125°C) temperature range. Both are available in narrow 16-lead SOIC surface-mount packages and 16-lead TSSOP.

REV. B CMP401/CMP402 –4– CAUTION ESD (electrostatic discharge) sensitive device. 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!
