CD4066 as a 4 pole switch?

[Leftrights]

Does anyone know anything about using a CD4066 as a 4 pole switch.  It seems like this is where CMOS switching would really "shine" :wink: , replacing those expensive hard to find mechanical ones.

I know that the full answer to this question is probably the length of a whole artical so could someone tell me even where to start looking?

Is there 4 "state" (is that even the right word??) equivilant to a flip flop?

I also posted an idea using this chip a few weeks ago, but it still needs a little work.  It used one half of the chip as a flip-flop and the other half for Boss type bypass.

That would work, of course. But you could also use the CD4051 one-to-four CMOS switch.

I agree with R.G. that you could use a multiplexer which would simplify the layout for the audio side. You would still need to do some other logic to switch through the various switches but thats the case in all situations. Oh and I think he meant the CD4052 which is 4 channels. CD4051 is 8 channels.

If you really have your heart set on using a 4066 then the "4 state flip-flop" as you call it is really called a shift register. Check out the Vanishing Point thread on how to use one to control a 4066 switcher. It uses a slightly exotic IC, 40194, but you could build one easily out of a pair of 4013 dual flip-flops that would fit your needs. That way it can built out of parts that you can find easily or order from suppliers like Small Bear.
