81CXXX/81NXXX CMOS IC is a high-precision, low-power voltage detector with a built-in delay circuit, extremely high accuracy and minimal temperature drift. Both CMOS and N-channel open drain output configurations are available.
The document describes the UTC 81CXXX and 81NXXX series, which are highly accurate, low power consumption CMOS ICs manufactured by Unisonic Technologies. These devices function as voltage detectors with a built-in delay circuit, eliminating the need for external peripherals to achieve high density mounting.
