Overview
The TS3704IDT, produced by STMicroelectronics, is a micropower CMOS quad voltage comparator. It is characterized by its extremely low power consumption of 9µA typical per comparator, which is 20 times less than the bipolar LM339. This component features a push-pull CMOS output stage, eliminating the need for an external pull-up resistor and thus saving power and space. The TS3704IDT maintains response times similar to the LM339 despite its low power consumption.
