Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to
the device may occur. Operating Ratings indicate conditions for which the
device is intended to be functional, but do not guarantee specific perform-
ance limits. For guaranteed specifications and test conditions, see the Elec-
trical Characteristics. The guaranteed specifications apply only for the test
conditions listed.
