Absolute Maximum Ratings
(Note 3)
Recommended Operating
Conditions
(Note 5)
Note 3:
The
“
Absolute Maximum Ratings
”
are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the
“
Electrical
Characteristics
”
table are not guaranteed at the Absolute Maximum Rat-
ings. The Recommended Operating Conditions tables will define the condi-
tions for actual device operation.
Note 4:

Absolute Maximum Rating must be observed.
Note 5:
Floating or unused pin (inputs or I/O's) must be held HIGH or LOW.
