3.3V Min is at 3.6V, Max is at 3V.
5V Min is at 5.5V, Max is at 4.5V.
CPD is used to determine the dynamic power consumption per flip-flop.
Note:

AC: PD = CPD VCC 2 fi = ∑ (CL VCC 2 fo)

ACT: PD = CPD VCC 2 fi + ∑ (CL VCC 2 fo) + VCC ΔICC where fi = input frequency, fo = output frequency, CL = output load capacitance, VCC = supply voltage.
