The LM2903N is made up of two separate voltage comparators that can operate over a wide variety of voltages from a single power supply. Dual-supply operation is also conceivable if the difference between the two supplies is between 2 and 36 V and VCC is at least 1.5 V higher than the input common-mode voltage. The supplied voltage has no effect on the current drain. To achieve wired-AND relationships, the outputs can be coupled to other open-collector outputs.
