[sdiy] CD4066/4016 Question

[harrybissell]

I ground them all...

Its best to consider them as 'inputs' when in doubt...  They cannot source or
sink current on their own so you can connect them as you like. But I see no
advantage in tying one "input" low... and turning the switch 'on' to protect
the other "output"

all ground
