(1) 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.

(1) 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.
(2) For packages with exposed thermal pads, such as QFN, PowerPAD™, or PowerFLEX™, θ_JP is defined as the thermal resistance
between the die junction and the bottom of the exposed pad.
