With a mux, you have multiple inputs ... This means that a single input can be directed to 2 or 4 outputs respectively. Some muxes can switch multiple signals, so you’ll see something like ...

There are five input pins ... that the mux chip can operate rail-to-rail. However, for some applications, you’ll need a negative supply and the device can accept a +/- 2.5V supply for that ...

clock gating checks need to be met at the inputs. However, there is a design-dependency when applying clock gating checks on this multiplexer which we will be explaining below. Figure 2 : CLK_D1 ...
