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 1012 ), 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.
