description  
These quadruple differential comparators are  
fabricated using LinCMOS technology and  
NC – No internal connection  
consist of four independent voltage comparators  
designed to operate from a single power supply.  
Operation from dual supplies is also possible if the  
difference between the two supplies is 2 V to 18 V.

impedance (typically greater than 10  
),  
allowing direct interfacing with high-impedance  
sources. The outputs are n-channel open-drain  
configurations and can be connected to achieve  
positive-logic wired-AND relationships.  
The TLC374 has internal electrostatic discharge (ESD) protection circuits and has been classified with a 1000-V  
ESD rating using human body model testing. However, care should be exercised in handling this device as  
exposure to ESD may result in degradation of the device parametric performance.  
The TLC374C is characterized for operation from 0°C to 70°C. The TLC374I is characterized for operation from  
40° to 85°C. The TLC374M is characterized for operation over full military temperature range of  
55°C to 125°C. The TLC374Q is characterized for operation from 40°C to 125°C.
