16-channel analog multiplexer/demultiplexer
[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 µW).
PD = CPD × VCC2 × fi + ∑{(CL +Csw) × VCC2 × fo} where:
fi = input frequency in MHz;
fo = output frequency in MHz;
∑{(CL +Csw) × VCC2 × fo} = sum of outputs;
CL = output load capacitance in pF;
Csw = switch capacitance in pF;
VCC = supply voltage in V.
Table 10.
Dynamic characteristics 74HCT4067
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.
