description
These quadruple differential comparators are
fabricated using LinCMOS
technology and
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.
Each device features extremely high input
impedance (typically greater than 10
12
),
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.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:
1. All voltage values except differential voltages are with respect to network ground.
2. Differential voltages are at IN+ with respect to IN .
3. Short circuits from outputs to VDD can cause excessive heating and eventual device destruction.
