[1] Typical values are measured at nominal supply voltage (VCC = 3.3 V and VCC = 5.0 V).
[2] tpd is the same as tPLH and tPHL
ten is the same as tPZL and tPZH
tdis is the same as tPLZ and tPHZ

.
[3] CPD is used to determine the dynamic power dissipation PD (µW).
PD = CPD × VCC2 × fi + ∑(CL × VCC2 × fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
VCC = supply voltage in Volts.
