LM339 Quad Voltage Comparator 14-Pin SOIC(SMD Package)The LM339 is a quad voltage comparator with a 14 pin SOIC package. The LM339 is made up of four independent voltage comparators that are designed to operate over a wide voltage range from a single power supply. These comparators are intended for use in level detection, low level sensing, and memory Applications in automotive, and industrial electronic Applications. Split power supply operation is also possible. Features Single or dual supply operation
