[1] tpd is the same as tPLH and tPHL.

[2] ten is the same as tPZH and tPZL.

[3] tdis is the same as tPLZ and tPHZ.

[4] CPD is used to determine the dynamic power dissipation (PD in μW):

PD = CPD x VCC2 x fi + ∑{(CL + Csw) x VCC2 x fo} where:

fi = input frequency in MHz;

fo = output frequency in MHz;

∑{(CL + Csw) x VCC2 x fo} = sum of outputs;

CL = output load capacitance in pF;

Csw = switch capacitance in pF;

VCC = supply voltage in V.
