Overview
The TLC3702MDR, produced by Texas Instruments, is a dual micropower voltage comparator designed to operate from a single supply. It is compatible with modern HCMOS logic systems and offers high performance with low power consumption. The device consists of two independent comparators, each featuring a push-pull CMOS output stage that can drive capacitive loads directly without the need for a power-consuming pullup resistor. This design reduces power dissipation, saves board space, and minimizes component cost. The TLC3702MDR is functionally similar to the LM339 but uses one-twentieth of the power for similar response times.
