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. www.national.com 4 |
