2 Description

This device is fabricated using CMOS 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 2.7V to 18V. Each device features extremely high input impedance (typically greater than 1012Ω), 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 2.7V supply makes this device an excellent for low-voltage battery applications.

The TLC352 has internal electrostatic discharge (ESD) protection circuits and is classified with a 2000V ESD rating. However, care must be exercised in handling this device as exposure to ESD can 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.
