Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics.
Note 2: The maximum allowable power dissipation is a function of the maximum junction temperature, T
and the ambient temperature, T
maximum power dissipations of 2.6W is determined using T
characteristics table is measured with the part surface mounted to a 2" x 2" FR4 4 layer board. See Figure 10 for more detailed θ
Note 3: The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor to each pin.
