The external component is calculated using:
The frequency f includes driving the load high and then back
low. For example: DATA15–0 pins can drive high and low at a
maximum rate of 1/(23t
A typical power consumption can now be calculated for these
conditions by adding a typical internal power dissipation.

while 100% of the output pins are switching from all ones (1s) to
all zeros (0s). Note also that it is not common for an application
to have 100%,or even 50%, of the outputs switching
simultaneously.
