It presents switching of 2 sources using CMOS CD4016 Analog Switch into a single channel.
My question is, how can I switch 4 sources using a 'single clock'.
Here is my 'complex' interpretation,
Use clock to run one mod-4 asynchronous counter with outputs Q0, Q1.
Then construct one 'logic circuit' to drive 4016 according to the truth table given in the
I don't understand exactly what you want to do. Do you want switch the 4 sources to a single input? or do you want to switch the 4 sources to 4 inputs, in other words do just want to switch the 4 source off and on?

A CD4016 is very old and has a high on-resistance. A CD4066 is improved with a much lower on-resistance.
A CD4052 has two improved switches that are one input to 4 outputs or 4 inputs to one output. The switches have two binary control inputs.
You can use a counter with decoded output such as the CD4017 or the CD4022. These outputs can drive the 4016 or 4066 directly.
Be aware though, that if you set Vss to a negative voltage for the switch to carry analog signals, then the digital control signals need to go between Vss and Vdd, not between Vdd and ground.
