LM139 Datasheet | National Semiconductor

Description The LM139 series consists of four independent precision voltage parators with an offset voltage specification as low as 2 m V max for all four parators. These were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. These parators also have a unique characteristic in that the input mon-mode voltage range includes ground, even though operated from a single power supply voltage. Application areas include limit parators, simple analog to digital converters; pulse, squarewave and time delay generators; wide range VCO; MOS clock timers; multivibrators and high voltage digital logic gates.
