LP239 Datasheet (Texas Instruments) - Low-Power Quad Differential Comparator

LP239, Low-Power Quad Differential Comparator

ordering information The LP239, LP339, LP2901 are low-power quadruple differential comparators.

Each device consists of four independent voltage comparators designed specifically to operate from a single power supply and typically to draw 60-µA drain current over a wide range of voltages.

Operation

The LP239 is obsolete and is no longer supplied.
