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 Prerequisite for Switching PARAMETER SYMBOL VCC (V) 25oC0oC TO 70oC UNITS TYP MIN MAX Data to Latch Enable Setup Time tSU 5 (Note 8) -2- ns Data to Latch Enable Hold Time tH 5 - 1.5 - ns Latch Enable Pulse Width CD74FCT573 tW 5-6- ns CD74FCT573AT tW 5-5- ns NOTE: 8. 5V: Minimum is at 4.75V for 0oC to 70oC, Typical is at 5V.
