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

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.
