Typical values are measured at Tamb =25 C and VCC = 1.2 V, 1.8 V, 2.5 V, 2.7 V and 3.3 V respectively.

tpd is the same as tPLH and tPHL.
[3]
Skew between any two outputs of the same package switching in the same direction. This parameter is guaranteed by design.

CPD is used to determine the dynamic power dissipation (PD in W).
PD =CPD VCC2 fi N+ (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
