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: 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
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.
