C_PD, measured per
P_D (per package) =
flip-flop, is used to determine the
V_CC I_CC + Σ(V_CC2 f_I C_PD + V_O2
dynamic power consumption.
f_O C_L + V_CC ∆I_CC D) where:
V_CC = supply voltage
∆I_CC = flow through current x unit load
C_L = output load capacitance
D = duty cycle of input high
f_O = output frequency
f_I = input frequency
