General Description

The HT70xxA-2 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 8.2V. The

voltage detectors consist of a high-precision and low

power consumption standard voltage source as well as a

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.

Note:

²xx² stands for output voltages.

Both lead free and green compound devices are available. Note the symbol marks below:

²#² stands for lead free devices.

²+² stands for green compound devices, which are Lead-free and Halogen-free.

For the TO92 package, the symbol mark will be at the end of the date code. Whereas for the SOT89 and

SOT23-5, the symbol mask will be located at the end of IC marking.
