hi forum,
I've designed a "keyboard sniffer/simulator" with 16 channels input/output - basic working is: a uC receives signals from 16 channels input (keyboard or other), and replicates them via 2x16 channels mux (4067d) - it also comunicates with other board in between via RX/TX bus...
example: if I have COL1 and ROW1 connected on input, I replicate it on output by controlling both mux"ABCD" inputs.
Anyway, I need to do the same but with 32 channels now... and using 32:1 mux seems not to be an option due to high cost of such components (ex = ADG732)! I planned to duplicate the 2x16 channels configuration and control the setup with the uC (ABCD + ENABLE) but wonder if there's out there some 4067D equivalent with 32 channels, or any other simple way to do the job...
Thanks for looking.
