[1] tpd is the same as tPHL and tPLH.
[2] ten is the same as tPZH and tPZL.
[3] tdis is the same as tPHZ and tPLZ.
[4] tt is the same as tTHL and tTLH.
[5] 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 outputs.
