Typical values are measured at nominal supply voltage (VCC = 3.3 V and VCC = 5.0 V).

tpd is the same as tPLH and tPHL.
[3]
tpd is the same as tPHL only.

CPD is used to determine the dynamic power dissipation (PD in W).
PD =CPD × VCC2 × fi × N+ Σ(CL × VCC2 × fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
VCC = supply voltage in V;
N = number of inputs switching;
Σ(CL × VCC2 × fo) = sum of the outputs.
