16-channel analog multiplexer/demultiplexer
Table 9. Dynamic characteristics 74HC4067 â¦continued
GND = 0 V; tr = tf = 6 ns; CL = 50 pF unless specified otherwise; for test circuit see Figure 14.
Vis is the input voltage at a Yn or Z terminal, whichever is assigned as an input.
Vos is the output voltage at a Yn or Z terminal, whichever is assigned as an output.

[1] tpd is the same as tPHL and tPLH.
[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] ton is the same as tPHZ and tPLZ.
[4] toff is the same as tPZH and tPZL.
[5] CPD is used to determine the dynamic power dissipation (PD in ïW).
PD = CPD ï´ VCC2 ï´ fi + ï¥{(CL + Csw) ï´ VCC2 ï´ fo} where:
fi = input frequency in MHz;
fo = output frequency in MHz;
ï¥{(CL + Csw) ï´ VCC2 ï´ fo} = sum of outputs;
CL = output load capacitance in pF;
Csw = switch capacitance in pF;
VCC = supply voltage in V.
