CPD, measured per flip-flop, is used to determine the dynamic power consumption. PD (per package) = VCC ICC + Σ(VCC 2 f I CPD + VO 2 f O 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 CD74FCT540, CD74FCT541 |
