3 DESCRIPTION AND ORDERING INFORMATION
This device consists of a single voltage comparator designed to operate from a single power supply over a wide
range of voltages. Operation from dual supplies also is possible if 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. To achieve wired-AND relationships, one can connect the output to other
open-collector outputs. …
