Hello Bill,
If you look at the HCT405x specs you'll see that they specified very
different leakage values for the 4051 versus the 4052 and 4053. They've
got to have a reason for that.
My impression is that CMOS processes for the logic families are a whole
lot better in variations than they were 20 years ago. And I have heard
quite some horror stories about the situation 30 years ago.
Regards, Joerg
The manufacturer's specified leakage current specification used to be
set by the limitiations of their measuring gear and the time available
to take the measurement.

I don't know how leaky modern CMOS has become.
