I have a system where I have a 328 hooked up to a 74HC4067 in order to talk to 16 sensors over SPI. The lines of the mux are connected to the slave select pins on each of the 6 sensors, so I can choose a sensor to talk to and transfer data. The only problem is, slave select is disabled for a high voltage and enabled for a low.
As a result, I am looking for a way for the mux to output a high signal on all pins BUT the one I have chosen. Essentially the inverse signal. What I'm seeing in the data sheet is for a chart that does just that, but I'm not sure how to get it. Any ideas?
