Overview
The TLC3702ID, produced by Texas Instruments, is a dual micropower voltage comparator integrated circuit. It consists of two independent voltage comparators designed to operate from a single supply and is compatible with modern HCMOS logic systems. These comparators are functionally similar to the LM339 but consume one-twentieth of the power while maintaining similar response times. The TLC3702ID is part of the LinCMOS™ family, which offers superior analog performance, low power consumption, high input impedance, and low bias currents.
