GND = 0 V; tr = tf = 6 ns; CL = 50 pF; for test circuit see Figure 15.
Vis is the input voltage at a Yn or Z terminal, whichever is assigned as an input.
os is the output voltage at a Yn or Z terminal, whichever is assigned as an output.

ton is the same as tPZH and tPZL
.
[3] toff is the same as tPHZ and tPLZ
.
[4] CPD is used to determine the dynamic power dissipation (PD in W).
PD = CPD VCC2 fi N + {(CL + Csw) VCC2 fo} where:
fi = input frequency in MHz;
fo = output frequency in MHz;
N = number of inputs switching;
{(CL + Csw) VCC2 fo} = sum of outputs;
CL = output load capacitance in pF;
Csw = switch capacitance in pF;
VCC = supply voltage in V.
