[1] t_pd is the same as t_PLH and t_PHL.
[2] t_en is the same as t_PZH and t_PZL.
[3] t_dis is the same as t_PLZ and t_PHZ.
[4] C_PD is used to determine the dynamic power dissipation (P_D in µW):
P_D = C_PD × V_CC2 × f_i + ∑{(C_L + C_sw) × V_CC2 × f_o} where:
f_i = input frequency in MHz;
f_o = output frequency in MHz;
∑{(C_L + C_sw) × V_CC2 × f_o} = sum of outputs;
C_L = output load capacitance in pF;
C_sw = switch capacitance in pF;
V_CC = supply voltage in V.
