DESCRIPTION

This device consists of two independent low

power voltage comparators designed specifically

to operate from a single supply over a wide range

of voltages. Operation from split power supplies is

also possible.

These comparators also have a unique

characteristic in that the input common-mode

voltage range includes ground even though

operated from a single power supply voltage.
