Stresses beyond those listed under “absolute maximum
i ratings” may cause permanent damage to the device. These
are stress ratings only, functional operation of the device at
f these or any other conditions beyond those indicated under
“recommended operating conditions” is not implied. Exposure
n to absolute maximum-rated conditions for extended periods
Co may affect device reliability.
