GENERAL DESCRIPTION  
2v  
50mV  
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 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 indus-  
trial (–40°C to +125°C) temperature range. Both are available in  
narrow SO-16 surface-mount packages and 16-lead TSSOP.

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!
