The STMicroelectronics Low power quad voltage comparator consists of four independent precision voltage comparators. Each comparator has been designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible. These comparators also have a unique characteristic in that the input common mode voltage range includes ground even though operated from a single power supply voltage.

Input common mode voltage range includes ground
Low output saturation voltage
Differential input voltage range equal to the supply voltage
