We've made accessing voltages easier for you. This LM339 Quad Comparator is made to function from a single power supply over a selection of voltages. Operation from dual supplies is also possible if supplies have a difference of 2V to 36V and VCC is at least 1.5V more positive than the input common-mode voltage.
