3 Description
This device consists of two independent voltage
comparators that are designed to operate from a
single power supply over a wide range of voltages.
Operation from dual supplies 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.
