  • I don’t get it either. If you select one of the mux chips, and select one of the pins on that mux by changing the control pins, then write a ‘1’ to that pin, then you change the control pins on that mux to a select different pin, what happens to the state of the previous pin? It the ‘1’ latched or not?
