DESCRIPTION/ORDERING INFORMATION

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

voltage. Current drain is independent of the supply voltage. The outputs can be connected to other

open-collector outputs to achieve wired-AND relationships.
