Description

The LM2901x-Q1 family of devices consists of four independent voltage comparators, designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies is possible, provided the difference between the two supplies is
2 V 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 other open-collector outputs to achieve wired-AND relationships. LM2901V-Q1 supports higher VCC voltage and LM2901AV-Q1 supports higher VCC and lower VIO.
