Product Summary
The LM293DR is a dual differential comparator. The LM293DR consists 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 also is possible as long 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 is independent of the supply voltage. The outputs of the LM293DR can be connected to other open-collector outputs to achieve wired-AND relationships. The LM293DR is characterized for operation from -55 to 125℃.
