Product Summary

The LM293P is a dual differential comparator. The LM293P 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 2V to 36V, and VCC is at least 1.5V more positive than the input common-mode voltage. Current drain is independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve wired-AND relationships. The LM293P is characterized for operation from -25℃ to 85℃.
