General Description
The HT70XXA-1 series devices area set of three terminal
low power voltage detectors implemented in CMOS
technology. Each voltage detector in the series detects a
particular fixed voltage ranging from 2.2V to 5V. The
voltage detectors consist of a high-precision and low
power consumption standard voltage source as well as a

CMOS technology ensures low power consumption.
Although designed primarily as fixed voltage detectors,
these devices can be used with external components to
detect user specified threshold voltages.
