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. (2) This value is limited to 6 V maximum. (3) The package thermal impedance is calculated in accordance with JESD 51-7. 2 |
