[1] t_pd is the same as t_PLH and t_PHL.
[2] t_t is the same as t_THL and t_TLH.
[3] C_PD is used to determine the dynamic power dissipation (P_D in W).
P_D = C_PD  V_CC2  f_i  N + (C_L  V_CC2  f_o) where:
f_i = input frequency in MHz;
f_o = output frequency in MHz;
C_L = output load capacitance in pF;
V_CC = supply voltage in V;
N = number of inputs switching;
(C_L  V_CC2  f_o) = sum of outputs.
