Stresses beyond Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only and functional
operation 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. All voltages are with respect to GNDA.
