Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Conditions
are conditions under which the device functions but the specifications might not be guaranteed. For guaran-
teed specifications and test conditions see the Electrical Characteristics.
The maximum power dissipation is a function of the maximum junction temperature, T
