The LP339D is a quad low-power general purpose Differential Comparator designed specifically to operate from a single power supply and typically to draw 60μA drain current over a wide range of voltages. Operation from split power supplies is also possible and the ultralow power supply drain current is independent of the power supply voltage. The LP339 is specifically designed to interface with the CMOS logic family. The ultra-low power-supply current makes these products desirable in battery-powered applications. The LP339 is characterized for operation from 0 to 70°C.
