Where to use CD4052 IC 

The IC CD4052 is a CMOS-based high-voltage Multiplexer and Demultiplexer IC. The IC is commonly used in circuits where a 4:1 MUX or a 1:4 DEMUX is required in a Programmable Logic circuit Design. It can handle both analog and digital voltages hence can be used in Analog to Digital and Digital to Analog converters.

CD4052 as 4:1 Multiplexer:

The CD4052 can be used as a 4:1 Multiplexer, that is it can take inputs from 4-channel and convert it to single-channel output based in the channel select pins. In our case the four Input channels are X0Y0, X1Y1, X2Y2 and X3 and Y3 and the single output channel is X,Y. The output on the single channel is decided based on the channel select pins A and B. The state of the select pins and channel selection is shown in below table:

A B Channel Selected
0 0 Channel 0
1 0 Channel 1
0 1 Channel 2
1 1 Channel 3

The complete working of a 4:1 MUX using the CD4052 simulation is shown in the video below, the image here shows a snapshot of it.

CD4052 Multiplexer Circuit Diagram

As you can see in the above image, the channel select pins are 1 and 0 for A and B respectively. This means Channel 1 which is X1 and Y1 is selected. So the input given to X1 and Y1 is reflected on the pins X and Y.

CD4052 as 1:4 Demultiplexer:

The CD4052 can be used as a 1:4 Demultiplexer also, that is it can take one input and provide it to either one of the 4 output channels based on the channel select pins. Here the input pins will be X and Y. The output pins can either be X0,Y0 or X1,Y1 or X2,Y2 or X3,Y3 based on the value set on A and B pins. We have already discussed how to select the channel using pins A and B in the above table.

CD4052 Demultiplexer Circuit Diagram

The above image shows the simulation of CD4052 in a demultiplexer circuit, the complete working can be found in the video linked below. As you can see here, channel 2 is selected by making A as 0 and B as 1. Hence the input given to pin X and Y is reflected on the channel 2 X2 and Y2 pins.

Applications
  • Multiplexer and Demultiplexer circuit
  • A/D and D/A converter circuits
  • Network switching
  •  Programmable Logic circuits.
