† _{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.
