*Stresses above those listed under âAbsolute

Maximum Ratingsâ 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.
