First, I apologise for not posting this under 'project guidance'. I couldn't get it to post there. Whenever I post in that forum, I seem to sign out automatically.
On to the issue: I'm trying to build a circuit that switches between two signals, for 20 something outputs. So, I deliver the 20 inputs and the 20 outputs take on either the one or the other signal. Google seems to point me to the 4066 or a 74HC244.
Reading the datasheets of the 4066, I can't figure out where I put my two input signals. As I understand it now, I apply one of the signals to each of the four input (Y) pins and my selection to the enable. Then, on a second 4066 I apply the second signal and use the inverse of my selection to the enable. Correct?
I'm a bit confused by this, as this seems more like 'channel selection' rather than 'channel switching'. Also, it seems like a circuit this could be solved in a single package.
I'm thinking along the lines of:
Does this exist? And in case the 4066 actually does this, what am I missing?
Is there an IC which does this
