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

Part No.

²XX² stands for output voltages.

For lead free devices, TO-92 package will add a ²#² mark at the end of the date code, whereas SOT-89 &

SOT-25 packages will add a ²#² mark at the end of the marking.

comparator, hysteresis circuit, and an output driver.

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.
