Product Summary
The LM193DR is a kind of dual differential comparator. It includes two independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. The LM193DR operation from dual supplies also is possible aslong as 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 of the LM193DR is independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve wired-AND relationships.
