† Notice: Stresses above those listed under "Absolute Maxi-
mum 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 indicated
in the operation sections of the specifications is not implied.
Exposure to Absolute Maximum Rating conditions for
extended periods may affect device reliability.
