4052 Dual 4-Channel Analog Multiplexer/Demultiplexer DIP-16

4-Channel Multiplexer and Demultiplexer IC

The CD4052 is a 4-Channel Multiplexer and Demultiplexer IC. It can either be used as a 4:1 Multiplexer or a 1:4 Demultiplexer. The IC supports both Analog and Digital voltages and is hence widely used in many designs.

Where to Use CD4052 IC

The IC CD4052 is a CMOS-based high-voltage Multiplexer and Demultiplexer IC. Therefore, 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. Furthermore, since it can handle both analog and digital voltages, it’s perfect for use in Analog-to-Digital and Digital-to-Analog converters.

CD4052 as a 4:1 Multiplexer

The CD4052 can be used as a 4:1 Multiplexer, meaning it can take inputs from four channels and convert them to a single-channel output based on the channel select pins. In this case, the four input channels are X0Y0, X1Y1, X2Y2, X3, and Y3, while the single output channel is X, Y. Ultimately, 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 the table below:

CD4052 as a 1:4 Demultiplexer

Conversely, the CD4052 can be used as a 1:4 Demultiplexer. In other words, it can take one input and provide it to one of the four output channels based on the channel select pins. Here, the input pins will be X and Y. The output pins can be X0, Y0, or X1, Y1, or X2, Y2, or X3, Y3, depending 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.)

The above image shows the simulation of the CD4052 in a demultiplexer circuit; the complete working can be found in the video linked below. Specifically, as you can see here, channel 2 is selected by making A as 0 and B as 1. Therefore, 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.
