This is completely from memory, but I believe there is a difference
between the 4066 and the 74LS4066, and I *thought* the 74LS4066
allowed for a larger voltage swing which I *thought* was +/- 15v.

But I could have it backwards, anyone have a some reference books to
verify this?

The 4016 and the 4066 also had different voltage ranges, and different
internal resistances.
