Overview
The TLC3704CPWR is a quad micropower voltage comparator produced by Texas Instruments. It is designed to operate from a single supply and is compatible with modern HCMOS logic systems. This component is functionally similar to the LM339 but uses significantly less power, approximately 1/20th, while maintaining similar response times. The TLC3704CPWR features a push-pull CMOS output stage that can drive capacitive loads directly without the need for a power-consuming pullup resistor, reducing power dissipation and saving board space and component cost.
