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 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 outputs can be connected to
other
open-collector
wired-AND relationships.
