Product Summary

The LM139J is a low power offset voltage quad comparator. The LM139J has a unique characteristic in that the input common-mode voltage range includes ground,even though operated from a single power supply voltage. Applications of the LM139J include: limit comparators, simple analog to digital converters, simple analog to erators; wide range VCO; MOS clock timers; multivibratorsand high voltaged igital logic gates.
