4x1 Multiplexer Hack

I discovered through some online research that a 4:1 MUX can be constructed out of three 2:1 MUXs.  Nice!

Now, the output doesn't need a logic inverter (NOT gate) because the inverting MUXs are cascaded together. 

Be sure to check out the circuit I did, which explains in more detail how I hacked a Binary to 7-segment Decoder into a MUX.  https://everycircuit.com/circuit/4846082110259200
