Capacitive Load Factor
Figure 34 shows the relationship between I/O output delay
and load capacitance. It allows a user to adjust the specified
output delay if the load capacitance is different than 50 pF.
For example, if the actual load capacitance is 120 pF, add
2.5 ns to the specified delay. If the load capacitance is 20
pF, subtract 0.8 ns from the specified output delay.
Figure 34 is usable over the specified operating conditions
of voltage and temperature and is independent of the output
slew rate control.
