Table 10. Dynamic characteristics 74HCT4067
GND = 0 V; t_r = t_f = 6 ns; C_L = 50 pF unless specified otherwise; for test circuit see Figure 14.
V_is is the input voltage at a Yn or Z terminal, whichever is assigned as an input.
V_os is the output voltage at a Yn or Z terminal, whichever is assigned as an output.

[1] t_pd is the same as t_PHL and t_PLH.
[2] Due to higher Z terminal capacitance (16 switches versus 1) the delay figures to the Z terminal are higher than those to the Y terminal.
[3] t_on is the same as t_PHZ and t_PLZ.
[4] t_off is the same as t_{PZH and} t_PZL.
[5] C_PD is used to determine the dynamic power dissipation (P_D in W).
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.
