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.
