Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is in-
tended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics.
Note 2: VEXT is not allowed to exceed (VCC+ 0.3V) or damage to the device may occur.
Note 3: Rating is for the human body model, a 100 pF capacitor discharged through a 1.5k
Ω resistor into each pin.
Note 4: The maximum power dissipation must be de-rated at elevated temperatures and is limited by TJMAX (maximum junction temperature), θJA
(junction-to-ambient thermal resistance) and TA (ambient temperature). The maximum power dissipation at any temperature is: PDissMAX = (TJMAX −TA)/ θJA up
to the value listed in the Absolute Maximum Ratings.
Note 5: Limits reflect initial accuracy.
Note 6: TJ = 85˚C, 1000 hours. Activation energy of 0.78eV used.
