Cd4051 circuit diagram.

These multiplexer circuits dissipate extremely low quiescent power over the full vdd vss and vdd vee supply voltage ranges independent of the logic state of the control signals. 1 cd4051 ch3130 multi channel demodulator circuit diagram this circuit is mainly composed of 8 channel analog switch cd4051 and voltage follower ch3130 etc. The input signal of the prohibition terminal inh of analog switch cd4051 is used to control the gating of voltage follower ch3130 thereby perform demodulation to multiple analog signals. Cd4052 is a dual 4 channel differential multiplexer demultiplexer ic which has two binary control inputs a and b.

Control of analog signals up to 15vp p can be achieved by digital signal amplitudes of 3 15v.

In multiplexer mode it takes 4 inputs from 4 channels and returns the output on channel x y. And an inhibit input.

The cd4051 analog multiplexers demultiplexers are digitally controlled analog switches having low on impedance and very low off leakage currents. For example if vdd 5v vss 0v and vee 5v analog signals from 5v to 5v can be controlled by digital inputs of 0 5v. Cd4051 pinout ultimate spacer height 10 pinout diagram helps us to understand the pins configuration of any equipment.

Programmable logic circuits sensors 3 description the cd405xb analog multiplexers and demultiplexers are digitally controlled analog switches having low on impedance and very low off leakage current. Cd 4051 completely labelled pinout diagram is shown in the figure below. Packages just show the different models of the same device. 1 2 3 4 5 more. Electrical characteristics hcf4051 6 15. The two binary input signals a and b are responsible for selecting channels that which channel should be turned on.
