How do I use a multiplexer?
I have a bunch of assorted multiplexer chips I purchased in a grab bag a while back. I want to get my self familiar with them at the most basic level. I understand what multiplexing is by definition only, but not enough to really understand how to use one.
How would I go about testing out the pins for example, or is it even possible to use just 1 multiplexer IC with a 555 ic for the clock to understand what is going on?
