Datasheet

UPC277G2, UPC393G2

Single Power Supply Dual Comparator

DESCRIPTION

UPC277, UPC393 are dual comparators designed to operate for a single power supply. The features include

low-voltage operation, a common-mode input voltage that range from V − (GND) level, an open collector output,

and low current consumption. Furthermore, these products can operate on a split power supply and used

widely for various voltage comparison application.

Depending on the usage and operating ambient temperature range, the UPC277 is design for communication

industries and UPC393 is design for general purposes.

In addition, compatible DC parameter selection for the comparators also available.

Along with this series of lineup, the quad type comparators, UPC177 and UPC339 with the same circuit

configuration are also available.
