Note 2: The Absolute Maximum Ratings are those values beyond which the

safety of the device cannot be guaranteed. The device should not be oper-

ated 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-

tual device operation.
