Stresses beyond those listed under “ absolute maximum ratings ” may cause permanent damage to the device. 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.
Maximum power dissipation is a function of T J (max), θ JA , and T A . The maximum allowable power dissipation at any allowable ambient
temperature is P D = (T J (max) – T A )/ θ JA . Operating at the absolute maximum T J of 150 ° C can affect reliability.
The package thermal impedance is calculated in accordance with JESD 51-7.
