CPD, measured per
PD (per package) =
flip-flop, is used to determine the
VCC ICC + Σ(VCC2 fI CPD + VO2
dynamic power consumption.
fO CL + VCC ∆ICC D) where:
VCC = supply voltage
∆ICC = flow through current x unit load
CL = output load capacitance
D = duty cycle of input high
fO = output frequency
fI = input frequency
