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

[2] tt is the same as tTHL and tTLH.

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

PD = CPD x VCC 2 x fi x N + ∑(CL x VCC 2 x 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;

∑(CL x VCC 2 x fo) = sum of outputs.

Measurement points are given in Table 8.

VOL and VOH are typical voltage output levels that occur with the output load.

Conditions: CP1 = LOW while CP0 is triggered on a LOW-to-HIGH transition and CP0 = HIGH, while CP1 is

triggered on a HIGH-to-LOW transition.
