Quote:But problem remains. Since dc voltage levels are inputs and some of them are smaller than threshold of transistor, what effect will they cause? Since all outputs are connected together at one node, what will happen when a particular tx gate turns off and other turns on?
Since the tx gates are composed of NMOS and PMOS, the dc voltage levels go to the output without any loss even if they are smaller than the threshold of transistors.
The input signals will conflict if only one tx gate off and others on.
