CAPACITIVE LOADING
Output delays and holds are based on standard capacitive loads:
30 pF on all pins (see Table 55). Figure 52 through Figure 57
show graphically how output delays and holds vary with load
capacitance. The graphs of Figure 48 through Figure 57 may not
be linear outside the ranges shown for Typical Output Delay vs.
Load Capacitance and Typical Output Rise Time (20% to 80%,
V = Min) vs. Load Capacitance.
