capacitance
[1] Typical values are measured at nominal supply voltage.
[2] t_pd is the same as t_PHL and t_PLH.
[3] t_pd is the same as t_PHL only.
[4] t_en is the same as t_PZL and t_PZH.
[5] t_dis is the same as t_PLZ and t_PHZ.
[6] C_PD is used to determine the dynamic power dissipation (P_D in W).
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  V_CC2  f_o) = sum of outputs;
C_L = output load capacitance in pF;
V_CC = supply voltage in V.
[7] All 9 outputs switching.
