Overview

µPC177GR-9LG, µPC339GR-9LG comparators are designed for single power supply operation. The features include low-voltage operation, common-mode input voltage range from V-(GND) level, open-collector output and low current consumption. Furthermore, these products can operate with both power supplies and can be widely used for various voltage comparison application. Depending on the usage and operating ambient temperature range, the µPC177GR-9LG is design for extended temperature and µPC339GR-9LG is design for general purposes. In addition, compatible DC parameter selection for the comparators are available under special products. Along with this series of lineup are dual type comparators, µPC277GR-9LG, µPC277MP-KAA, and µPC393GR-9LG with the same circuit configuration are also available
