Sir,

Is above Demultiplexer IC is programmable .if not please suggest IC which is programmed and control by python code.

Sayali,

The CD74HC4051 is a 8:1 multiplexer that selects which of the 8 paths are connected based on the truth table below. You can program the truth table by using the GPIOs from your microcontroller to supply the E and S pins with logic low voltages 0V or logic high voltages Vcc.

Do you have more information or a diagram of what you would like to connect to the 8:1 multiplexer and what type of device you are using to control it?

Thank you,

Adam

Sir,
Actually I want to use it as Demux ,I have PCB assembled board which consist of inverter,opam,head phone amplifier etc ,I want give input voltage from NI virtual bench to this each section from single supply one at time.I want IC or processor which can control this function.NI virtual bench can code through python.please suggest.

Sayali,

You may use the CD74HC4051 as a demux but you will need a separate device to control the logic pins. I'm going to move this thread to the processors forum to have a recommendation.

Thank you,

Adam

Hi Sayali,

If I understand you correctly, you want to use an MCU to control the logic pins of the demux to control where the output of the NI virtual bench is going. For this, assuming you are just using the MCU for this logic control, you could use one of our lowest cost MSP430 MCUs, such as the MSP430FR2000. Please note that you will write the code for these devices in C, not python. For a full list of MSP430 parts that you can search using the parameters you need, please see this link: www.ti.com/.../products.html
