Stresses at or above those listed under “Absolute Max-
imum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional oper-
ation of the device at these or any other conditions
above those indicated in the operational sections of
this specification is not implied. Exposure to absolute
maximum rating conditions may affect device reliability.
The power dissipation is based on the maximum allow-
able die temperature and the thermal resistance of the
package.
