Hi guys!

I need to redirect voltage from the input to one of many outputs, in sequence, everytime I put a voltage pulse on the input pin.
Imagine there are 16 outputs available, I connect a led to each output and I want that everytime I pulse the single input, it turns of the previous led and turns on the next led, like some sort of sequential switcher but I have merely one or two PIC pins availables to control the multiple output device.
Does someone know if such thing exist? Maybe a Demultiplexer of some kind?

Thanks for your help

Thanks, I knew this one.
It needs 4 lines input (2e4) but I need to use 1 input and one strobe line.
