[1] tpd is the same as tPLH and tPHL.
[2] CPD is used to determine the dynamic power dissipation PD (ïW).
PD = CPD ï´ VCC2 ï´ fi + ï¥ (CL ï´ VCC2 ï´ fo) where:
fi = input frequency in MHz; fo = output frequency in MHz
CL = output load capacitance in pF; VCC = supply voltage in Volts
ï¥ (CL ï´ VCC2 ï´ fo) = sum of outputs
