[1] All typical values are measured at T_amb = 25 °C.
[2] 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.
[3] C_PD is used to determine the dynamic power dissipation P_D (μW).
P_D = C_PD × V_CC2 × f_i + Σ((C_L × C_SW) × V_CC2 × f_o) where:
f_i = input frequency in MHz;
f_o = output frequency in MHz;
C_L = output load capacitance in pF;
C_SW = maximum switch capacitance in pF (see Table 7);
V_CC = supply voltage in volts;
Σ((C_L × C_SW) × V_CC2 × f_o) = sum of outputs.
