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. (3) All voltage values are with respect to network ground terminal. (4) ESD testing is performed according to the respective JESD22 JEDEC standard.
