Overview
The TS3704IPT is a micropower quad CMOS voltage comparator produced by STMicroelectronics. This component is designed for extremely low power consumption, making it ideal for applications where energy efficiency is crucial. The TS3704IPT features a push-pull CMOS output stage, eliminating the need for an external pull-up resistor, which saves power and space. It is pin-to-pin and functionally compatible with the bipolar LM339, but offers significantly lower power consumption.
