23.3.6
Figure 23.75 is a chart showing the changes in the delay time (reference data) when a load
capacitance equal to or larger than the stipulated value (30 pF) is connected to the LSI pins. When
connecting an external device with a load capacitance exceeding the regulation, use the chart in
figure 23.75 as reference for system design.
Note that if the load capacitance to be connected exceeds the range shown in figure 23.75 the
graph will not be a straight line.
