CMOS IC
DESCRIPTION
The UTC
88CXX
series are highly accurate, low power
consumption voltage detector, manufactured using CMOS process.
The detection voltage is fixed internally, with an accuracy of ±2.0%.
Besides, UTC
88CXX
can easily delay a release signal by
attachment of an external capacitor with built-in delay circuit.
