ST LM339AN

差分开集，轨至轨

Overview

The LMx39x and the LM2901x devices consist of four independent voltage comparators thatare designed to operate from a single power supply over a wide range of voltages. Operation fromdual supplies also is possible, as long as the difference between the two supplies is 2V to 36 V,and VCC 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 otheropen-collector outputs to achieve wired-AND relationships.
