(1) 3.3V Min is at 3.6V, Max is at 3V.

(2) 5V Min is at 5.5V, Max is at 4.5V.

(3) C_PD is used to determine the dynamic power consumption per flip-flop.

Note:

AC: P_D = C_PD V_CC ² f_i = ∑ (C_L V_CC ² f_o)

ACT: P_D = C_PD V_CC ² f_i + ∑ (C_L V_CC ² f_o) + V_CC ΔI_CC where f_i = input frequency, f_o = output frequency, C_L = output load capacitance, V_CC = supply voltage.
