abc corp,
There is an existing forums page discussing a 74HC4501... here:

If you cannot find an exact spice model for these, you could also try looking for a comparable component in our existing analog switch components - we have CMOS switches with several configurations similar to the HEF4051, 2 and 3. I am not exactly sure what you are looking at in terms of performance / model comparision but this should get you started.
From the Master DB, go to the 'Mixed' group and you will see the appropriate families.
From a modeling standpoint, you could build an equivalent functional level circuit in Multisim using the ideal analog switch and other ideal logic components. The ideal switch is located in our 'Mixed_Virtual' family.
