*Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
These are stress ratings only and functional operation of the
device at these or any other conditions above those indi-
cated in the operation sections of the specifications is not
implied. Exposure to Absolute Maximum Rating conditions
for extended periods my affect device reliability.
