PC277GR-9LG,
μ
PC277MP-KAA,
μ
PC393GR-9LG are dual comparators which are designed to operate for a
single power supply. It includes features of 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 be used for an extensive comparison of various voltages.
The
μ
PC277GR-9LG,

PC277MP-KAA which expands temperature type is suited for wide operating ambient
temperature use, and
μ
PC393GR-9LG is used for general purposes.
A DC parameter selection that is compatible to comparators is also available.
