The LM2903P devices consist of two independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies is also possible as long as the difference between the two supplies is within 2 V to 36 V, and VCC is at least 1.5 V more positive than the input common-mode voltage. Quiescent current is independent of the supply voltage, and the outputs can be connected to other open-collector outputs to achieve wired-AND relationships.
