(1) The maximum power dissipation must be derated at elevated temperatures and is dictated by T_JMAX, θ_JA and the ambient temperature,
T_A. The maximum allowable power dissipation at any temperature is P_D = (T_JMAX – T_A)/θ_JA. The values for maximum power dissipation
listed above will be reached only when the device is operated in a severe fault condition (e.g. when input or output pins are driven
beyond the power supply voltages, or the power supply polarity is reversed). Such conditions should always be avoided.
(2) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report, SPRA953.
