(1) Absolute Maximum Ratings are limits beyond which damage can occur. Operating Ratings are conditions under which operation of the
device is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated
test conditions, see the Electrical Characteristics tables.
(2) Junction to ambient thermal resistance is dependant on the application and board layout. In applications where high maximum power
dissipation is possible, special care must be paid to thermal dissipation issues in board design.
