description
This device is fabricated using LinCMOS
technology and consists of two independent
voltage comparators, each 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
Ω), 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 TLC372 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 a degradation of the device parametric performance.
The TLC372C is characterized for operation from 0°C to 70°C. The TLC372I is characterized for operation from
–40°C to 85°C. The TLC372M is characterized for operation over the full military temperature range of –55°C
to 125°C. The TLC372Q 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.
