[1] tpd is the same as tPLH and tPHL
[2] tt is the same as tTLH and tTHL
[3] CPD is used to determine the dynamic power dissipation (PD in ïW).
PD = CPD ï´ VCC2 ï´ fi ï´ N + 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 V;
N = number of inputs switching;
ï(CL ï´ VCC2 ï´ fo) = sum of the outputs.
