Overview
The TS393IPT is a micropower dual CMOS voltage comparator produced by STMicroelectronics. This device is known for its extremely low power consumption, typically 9 µA per comparator, which is significantly lower than its bipolar counterpart, the LM393. The TS393IPT offers similar performance to the LM393 but with the advantages of CMOS technology, including low input bias current and high input impedance. It is available in a TSSOP8 package, making it suitable for a variety of applications where low power and compact design are essential.
