† 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.
