† Stresses beyond those listed under “absolute maximum 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 beyond those indicated

under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for

extended periods may affect device reliability.

NOTE 1: All voltage values are with respect to VSS.
