Note 1:
Absolute maximum ratings indicate limits beyond which damage to the device may occur.
Operating ratings
indicate conditions for which the device
operates correctly.
Opearting Ratings
do not imply guaranteed performance limits.
Note 2:
The human body model is a 100pF capacitor discharged through a 1.5k resistor into each pin.
