Note 1: The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be op-
erated at these limits. The parametric values defined in the Electrical Charac-
teristics tables are not guaranteed at the absolute maximum ratings. The
“Recommended Operating Conditions” table will define the conditions for ac-
