Overview
The TLC3702MDREP, produced by Texas Instruments, is a dual micropower voltage comparator integrated circuit. It consists of two independent comparators designed to operate from a single supply voltage and is compatible with modern HCMOS logic systems. This device is functionally similar to the LM339 but consumes significantly less power while maintaining similar response times. The TLC3702MDREP is part of the LinCMOS family, which offers superior analog performance, low power consumption, high input impedance, and low bias currents.
