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 1.4 V to 18 V. Each device features extremely high input impedance
(typically greater than 10
12
Ω), which allows direct interface to high-impedance sources. The output are
n-channel open-drain configurations and can be connected to achieve positive-logic wired-AND relationships.
The capability of the TLC352 to operate from 1.4-V supply makes this device ideal for low-voltage battery
applications.
The TLC352 has internal electrostatic discharge (ESD) protection circuits and has been classified with a 2000-V
ESD rating tested under MIL-STD-883C, Method 3015. However, care should be exercised in handling this
device as exposure to ESD may result in degradation of the device parametric performance.
The TLC352C is characterized for operation from 0°C to 70°C. The TLC352I is characterized for operation over
the industrial temperature range of − 40°C to 85°C.
