General Description

The HT70XX series is a 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 2.4V to 7V. The voltage detectors consist of

a high-precision and low power consumption

standard voltage source, a comparator, hyster-

esis circuit, and an output driver. CMOS tech-

nology ensures low power consumption.

Although designed primarily as fixed voltage

detectors, these devices can be used with exter-

nal components to detect user specified thresh-

old voltages (NMOS open drain type only).
