This one was a surprise to me when I went looking. I'm building a custom audio processor for someone and I couldn't find something as simple as a 2-up dual mux in stock anywhere. I ended up finding a handful of DIP-package dual multiplexers in a drawer in my lab and using those. Luckily it occurred to me to check availability before doing a PCB layout and I only needed 3, but seriously! A basic analog switch was the last thing I though I'd have trouble finding.
