CPD, measured per function, is used to determine the dynamic power consumption. PD (per package) = VCC ICC +∑ (VCC 2 f l CPD + VO 2 f O CL + VCC ∆lCC D) where: VCC = supply voltage ∆lCC = flow through current x unit load CL = output load capacitance D = duty cycle of input high fO = output frequency fI= input frequency CD54FCT245, CD74FCT245 |
