Operating Temperature Ranges
Stresses beyond these listed under "Absolute Maximum
Ratings" may cause permanent damage to the device. These
are stress ratings only, and functional operation of the de-
vice at these or any other conditions beyond those indi-
cated in the operational sections of the specifications is
not implied. Exposure to absolute maximum rating condi-
tions for extended periods may affect device reliability.
