Note 4: Absolute Maximum continuous ratings are those values beyond
which damage to the device may occur. Exposure to these conditions or
conditions beyond those indicated may adversely affect device reliability.
Functional operation under absolute maximum rated conditions in not
implied.
Note 5: I_O Absolute Maximum Rating must be observed.
Note 6: Unused inputs must be held HIGH or LOW.
