Product Summary

These devices consist of four 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 can be connected to other open-collector outputs to achieve wired-AND relationships.
