LM339 Datasheet PDF
Part Number : LM339
Function : Quad Differential Comparators
Package : DIP ( LM339N, LM339AN ) or SMD ( LM339D, LM339AD ) 14 Pin Type
The LMx39x and the LM2901xx devices consist of four independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies also is possible, as long as the difference between the two supplies is 2 V to 36 V, and V CC is at least 1.5 V more positive than the input common-mode voltage. Current drain is independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve wired-AND relationships.
