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.
