[1] Typical values are measured at nominal supply voltage.

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

[3] tpd is the same as tPHL only.

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

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

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

PD = CPD x VCC 2 x fi + Σ(CL x VCC 2 x fo) where:

fi = input frequency in MHz;

fo = output frequency in MHz;

Σ(CL x VCC 2 x fo) = sum of outputs;

CL = output load capacitance in pF;

VCC = supply voltage in V.
