Daisy chaining74HC4067 #11

First, thx so much for this library! It works well and has made my life way easier :)

My problem is: I'm trying to daisy chain some 74HC4067. So far, I've been able to connect two 74HC4067, but each has its SIG0 pin connected to a different pin on the teensy, meaning I have to manage quite a few wires which is impractical.

Is there a way to chain them like we can chain 74HC165? If so, could you provide some guidance on how to do that, because I have not been able to figure it out from reading the docs, following the example, and doing a bunch of googling.. ^^

Thx!

You can only share the channel pins, each 4067 needs its own sig pin to the micro, your only other option which I've never tried is to use a single 4067 as the input for a bunch of other 4067s but at that point you'll also need independent channel pins for that 4067

I see. thx for the quick answer!

Are you aware of other chips that might provide this functionality? Basically PISO for analog input devices?
