Overview
The TS339IPT is a micro-power, CMOS, quad voltage comparator produced by STMicroelectronics. This device is characterized by its extremely low power consumption, with a typical supply current of 9 μA per comparator, which is 20 times less than the bipolar LM339. The TS339IPT offers similar performance to the TS3704 but with a focus on low power and high efficiency. It is pin-to-pin and functionally compatible with the bipolar LM339, ensuring seamless integration into existing designs.
