4 / 8 page 8-4 Switching Specifications Over Operating Range FCT Series tr, tf = 2.5ns, CL = 50pF, RL (Figure 4) (Note 6) PARAMETER SYMBOL VCC (V) 25oC0oC TO 70oC UNITS TYP MIN MAX Propagation Delays Clock to Q tPLH, tPHL 5 6.6 2 10 ns Output Disable to Q tPLZ, tPHZ 5 6 1.5 8 ns Output Enable to Q tPZL, tPZH 5 9 1.5 12.5 ns Power Dissipation Capacitance CPD (Note 7) -33- - pF Minimum (Valley) VOHV During Switching of Other Outputs (Output Under Test Not Switching) VOHV 5 0.5 - - V Maximum (Peak) VOLP During Switching of Other Outputs (Output Under Test Not Switching) VOLP 51 - - V Input Capacitance CI --- 10 pF Three State Output Capacitance CO --- 15 pF NOTES: 6. 5V: Min is at 5.25V for 0oC to 70oC, Max is at 4.75V for 0oC to 70oC, Typ is at 5V. 7. 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 Setup Time Data to Clock tSU 5 (Note 8) -2- ns Data to Clock Hold Time tH 5-2- ns Clock Pulse Width tW 5-7- ns Maximum Clock Frequency fMAX 5 - 70 - MHz NOTE: 8. 5V: Minimum is at 4.75V for 0oC to 70oC, Typical is at 5V.
