A.C. ELECTRICAL CHARACTERISTICS
A pin’s alternating-current (AC) characteristics include input and output capacitance. These factors
determine the loading for external drivers and other load analyses. The AC characteristics also
include a derating factor, which indicates how much the AC timings might vary with different
loads.
