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. NOTES: 1. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed. 2. This value is limited to 3.6 V maximum. 3. The package thermal impedance is calculated in accordance with JESD 51. 4. Connecting the NC-balls (C3, C4, D3, D4, G3, G4, H3, H4) to a ground plane improves the θJA to 114.8°C/W (0 airflow). |
