Operating Ratings indicate conditions for which the device is intended to be functional, but do not specific performance limits. For specifications and test conditions, see the Electrical Characteristics. (2) The maximum allowable power dissipation is a function of the maximum junction temperature, TJ_MAX, the junctions-to-ambient thermal resistance, θJA, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using: PD_MAX = (TJ_MAX – TA)/θJA. The maximum power dissipations of 2.6W is determined using TA = 25°C, θJA = 38°C/W, and TJ_MAX = 125°C. (3) The human body model is a 100 pF capacitor discharged through a 1.5 k Ω resistor to each pin.
