[1] t_pd is the same as t_PLH and t_PHL.
t_en is the same as t_PZL and t_PZH.
t_dis is the same as t_PLZ and t_PHZ.
[2] C_PD is used to determine the dynamic power dissipation P_D (µW).
P_D = C_PD × V_CC2 × f_i + ∑ (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 Volts
∑ (C_L × V_CC2 × f_o) = sum of outputs
