VCC = 3.0 V to 3.6 V
[1] 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.
[2] 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.
[4] PD is used to determine the dynamic power dissipation (PD in W).

C
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 Volts
N = number of inputs switching
(CL VCC2 fo) = sum of the outputs.
