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) The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed. (3) This value is limited to 3.6 V maximum. RθJA for TSSOP (DGG) Package (1) RθJA for MLF (RHA/RTB) Package RθJA for BGA (GQL/ZQL) Package (2) Airflow Low K High K Airflow With 4 Thermal Vias Airflow High K 0 ft/min 89.1 °C/W 70 °C/W 0 ft/min 44.7 °C/W 0 ft/min 132.2 °C/W 150 ft/min 78.5 °C/W 65.3 °C/W 150 ft/min 150 ft/min 126.4 °C/W (1) The package thermal impedance is calculated in accordance with JESD 51. (2) Connecting the NC-balls (C3, C4, D3, D4, G3, G4, H3, H4) to a ground plane improves the θ JA to 114.8°C/W (0 airflow). 5 Submit Documentation Feedback |
