Note 1: Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the

device is guaranteed. Operating Ratings do not imply guaranteed limits. For guaranteed performance limits and associated test conditions, see the Electrical

Characteristics table.

Note 2: The human body model is a 100pF capacitor discharged through a 1.5k

Ω resistor into each pin. The machine model is a 200pF capacitor discharged directly

into each pin.

Note 3: Current flows into the pin.

Note 5: Min and max limits are guaranteed by design, test, or statistical analysis. Typical numbers are not guaranteed, but do represent the most likely norm.
