STMicroelectronics LM139/LM239/LM339 Low-Power Quad Voltage Comparators Datasheet
This document describes the LM139, LM239, and LM339 families of low-power quad voltage comparators. These devices consist of four independent precision-voltage comparators designed to operate from a wide range of single or split power supplies. A unique characteristic is that the input common-mode voltage range includes ground even when operated from a single supply voltage.
