Output driver static; standard drive strength setting.
3.3 V CMOS; standard drive strength setting. Output toggle
rates in excess of the maximum are possible, but with reduced
amplitude (see Figure 12).
At maximum output frequency.
3.3 V CMOS; standard drive strength setting; 10 pF load.
1 The listed values are for the slower edge (rise or fall).
