6.1 Overview

The LV Family devices are micro-power comparators with open-drain outputs and improved input offset voltage that operate down to 1.65 V while only consuming only 25 µA per channel. The LV family are designed for portable, automotive and industrial applications. An internal power-on reset circuit makes sure that the output remains in a known state during power-up and power-down while fail-safe inputs can tolerate input transients without damage or false outputs.
