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

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.
