CD4052 4-Channel Multiplexer and Demulitplexer IC: Datasheet, Equivalent and Working

The CD4052 is a 4-channel analog/digital dual single-pole switch that can be used in analog or digital 4:1 multiplexer/demultiplexer applications. Each switch has four independent inputs and outputs as well as a common input and output. Both switches have a digital inhibit input (INH) and two digital select inputs (A and B). The switches are turned off when INH is HIGH.

CD4052 3D Model

• Wide range of digital and analog signal levels: digital 3 – 15V, analog to 15Vp-p

• Low “ON” resistance: 80Ω (typ.) over entire 15Vp-p signal-input range for VDD − VEE = 15V

• High “OFF” resistance: channel leakage of ±10 pA (Typ.) at VDD − VEE = 10V

• Logic level conversion for digital addressing signals of 3 – 15V (VDD − VSS = 3 – 15V) to switch analog signals to 15 Vp-p (VDD − VEE = 15V)

• Matched switch characteristics: ∆RON = 5Ω (Typ.) for VDD − VEE = 15V

• Very low quiescent power dissipation under all digital-control input and supply conditions: 1 µ W (typ.) at VDD − VSS = VDD − VEE = 10V

The CD4052 is a four-channel differential multiplexer/demultiplexer with two binary control inputs A and B. It accepts four inputs from four channels and outputs on channels X, Y, and an inhibit input in multiplexer mode. The two binary input signals A and B control which channels should be switched on.

The CD4052 IC can be used as a demultiplexer as well. It will only accept one input in this mode. The output will be routed to channel 0, 1, 2, or 3 depending on the selection pins A and B. Vss is connected to the circuit's ground, whereas Pin 15 is connected to the power supply. The inhibit pin is in charge of channel enabling and disabling. Channels are enabled when it is used with 0 logic. When the inhibit pin is applied with logic 1, no matter what input is applied on select pins, channels are disabled.

Use CD4052 as a Multiplexer

It has two channels, X and Y, in multiplexer mode. X0 to X3 for channel X, and Y0 to Y3 for channel Y, are the four inputs for each channel. X and Y are the output pins for both channels. For both 4 cross 1 muxes, input pins A and B serve as common selection lines. These selection lines determine which input signal is shown on the output pin.

This is a working circuit diagram. We are getting output on X and Y pins according to the above table. You may also experiment with it with Proteus. As you can see, pins A and B on the selection line are equal to one. Multiplexer chooses X3 and Y3 inputs based on the selection lines. As a result, these inputs appear on output pins like X and Y.

Use CD4052 as a Demux

This ic can also be used as a 14 multiplexer. It's also known as a decoder. X and Y are used as input pins in this setup. X0-X3 and Y0-Y3 on the other hand, use an output pin for X and Y, respectively. The selection pins A and B determine which pin output will be shown. As a result, based on digital logic on selected lines A and B, output pins will be X1, Y1 or X2, Y2 or X3, Y3 or X0, Y0.

The functioning principle of the demux is depicted in this simulation figure. As you can see in the figure, input X=1 and input Y=1 are both equal to zero, as are selection lines A and B. As a result, input signals appear on X0 and Y0. In other words, we can modify the values of the selection line signal to change the output.
