I'm looking for a device that will allow 4 momentry active low or high, don't mind, inputs to toggle a set of outputs.
When any of the buttons is pressed, it will set the other 3 outputs low, and set its output high.
Even better if it has an inbuilt binary encoder so that there are two outputs giving either 00, 01, 10, or 11.
True, but it would have to be a 16 pin chip I'm guessing and I'd like to avoid having to have any with the external oscillators, etc just for size reasons. Having said that, any discrete logic chips would probably be just as large!
I'll investigate!
I would use one of many 8 pin microcomputers. Four inputs 2 outputs gnd and supply. I have used the PIC12F508. At 100 pieces it is $0.60. If you need help with programming it, write me.
