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-

tual device operation.
