description
This device consists 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 is also possible so long as the difference
between the two supplies is 2 V to 28 V and V
is a least 1.5 V more positive than the input common-mode
CC
voltage. Current drain is independent of the supply voltage. The outputs can be connected to other
open-collector outputs to achieve wired-AND relationships.
