[1] CPD is used to determine the dynamic power dissipation (PD in W).
PD = CPD VCC2 fi + (CL VCC2 fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
(CL VCC2 fo) = sum of outputs.
CL = output load capacitance in pF;
VCC = supply voltage in V;
VI = GND to VCC for 74HC299;
VI = GND to (VCC 1.5 V) for 74HCT299.
