SINGLE POWER SUPPLY DUAL COMPARATORS WITH SMALL PACKAGE
<R> DESCRIPTION
The μ 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, μ 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.
μ PC177GR-9LG, μ PC339GR-9LG which are quad types with the same circuit configuration are also available as
series of comparators.
