CPD is used to determine the dynamic power dissipation (PD in μW).
PD = CPD × VCC2 × fi × N + Σ{(CL + Csw) × VCC2 × fo} where:
fi = input frequency in MHz;
fo = output frequency in MHz;
N = number of inputs switching;
Σ{(C
L + Csw) × VCC

× f
o} = sum of outputs;
CL = output load capacitance in pF;
Csw = switch capacitance in pF;
VCC = supply voltage in V.

Dynamic characteristics for 74HC4052 …continued
GND = 0 V; tr = tf = 6 ns; CL = 50 pF; for test circuit see Figure 15.
Vis is the input voltage at a nYn or nZ terminal, whichever is assigned as an input.
Vos is the output voltage at a nYn or nZ terminal, whichever is assigned as an output.
