NCX2222: Low Voltage Comparator; Open-Drain Output

Overview

The NCX2222 provides a dual, low voltage, low-power comparator with open-drain outputs.

The NCX2222 has a very low supply current of 5 μA per comparator and is guaranteed to operate at a low voltage of 1.3 V. It is fully operational up to 5.5 V which makes it convenient for use in both 3.0 V and 5.0 V systems.
