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. Maximum power dissipation is a function of TJ(max),θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD= (TJ(max)– TA)/θJA. Selecting the maximum of 150°C can affect reliability. 2. The package thermal impedance is calculated in accordance with JESD 51-5.
