DESCRIPTION
The UTC 81CXXX and 81NXXX series are good
performance voltage detector and manufactured by CMOS
technologies with highly accurate, low power consumption.
A
delay circuit is built-in to each detector, therefore, peripherals
are unnecessary and high density mounting is possible. Detect
voltage is extremely accurate with minimal temperature drift.
Both CMOS and N-channel open drain output configurations are
available.
