3 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 also is possible as
long as the difference between the two supplies is
2V to 28V and VCC is a least 1.5V 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.
