johnwasser- That's an interesting idea, could you elaborate any more on that? doesn't a counter just take a clock input, and have a single output? how could I control a mux with that?
It's not clear exactly what you want. Did you want an ANALOG multiplexer or DIGITAL? If DIGITAL, did you want 1 input and 8 outputs or 8 inputs and 1 output?
Let's assume analog. Take a CMOS counter like the TI CD4024B 7-stage ripple counter and connect the low three bits to the address inputs of the TI CD4051BC "Single 8-Channel Analog Multiplexer/Demultiplexer". Each pulse to the counter will select a different connection in the multiplexer.
With CMOS you have to be sure to tie all unused inputs HIGH or LOW. If an input is left floating it might turn on both of the Complimentary-symetry MOS transistors and try to drive a signal both HIGH and LOW. This can burn out your chip.
