Texas Instruments LM2903-Q1 Dual Differential Comparator
Texas Instruments LM2903-Q1 Dual Differential Comparator consists of two independent voltage comparators designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies is possible if the difference between the two supplies is 2V to 36V, and VCC is at least 1.5V more positive than the input common-mode voltage. The current drain is independent of the supply voltage. The outputs of the Texas Instruments LM2903-Q1 can be connected to other open-collector outputs to achieve wired-AND relationships.
