description/ordering information
This device consists of a single voltage comparator that is 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 V
CC
is at least 1.5 V more positive than the input common-mode voltage. Current drain is
independent of the supply voltage. The output can be connected to other open-collector outputs to achieve
wired-AND relationships.
