*Stresses greater than those listed above may cause permanent damage to the
device. These are stress ratings only, and functional operation of the device at these
or any other conditions greater than those indicated in the operational sections of
this specification is not implied. Exposure to absolute maximum rating conditions
for extended periods may affect device reliability.
