I'm designing a cape for a BeagleBone and I'd like them to be stackable. For this reason, I need to be able to put a cape into a particular "mode" such that the I/O goes to a different set of pins on the beaglebone for each cape. I plan to do this with a 4 channel multiplexer (I plan to stack up to three shields), but I have a total of 10 signals (possibly more later) that need to be switched concurrently. So far I've found a dual 4 channel multiplexer, but I need something that can handle 10 signals at once, not just two. Anyone know if such a chip exists?
