I did try save the model as a. The playground is a publicly-editable wiki about Arduino. The only difference will be the EN dataheet as it will datashret be active high instead of active low.

A multiplexer or demultiplexer enables you to expand the in-and outputs on your Arduino board. There is no delay needed between selecting and read or writing the pin. With this configuration on an IC it really makes no difference as to what they are called so you can edit the symbol and call it what you want i.

I think I see why the output may dahasheet very low perhaps – I put a 10K resistor between the output and ground and the output vanished. You can just cut a paste it into Notepad or some other text editor and edit it that way.

So my guess is that the switch isn’t switching. Each of these pins have to be connected to one digital out pin on the Arduino.

Multisim and Ultiboard

I tried to work out how to modify an exisiting model ADGFbut failed miserably, as I’m not able to infer the language syntax from the model content unlike the digital models which I could work out, albeit slowly. I don’t think that anyone has created this component in the past.


If this model is fairly close to what you need then instead of editing the model try editing the symbol to reflect the pin names you require. Message 6 of Also, in your original post you said the IC was 74hc, but the model file you posted says 74hc Message 3 of I know that it can be frustrating when the component you need is not there.

Can I take the model and write it to a. As far as the voltage pins. For more info pleae look at this Forum Post. An alternative approch might be to hack the model for the 74HC, but again, I wouldn’t know quite where to start! What have I done wrong please?

Board Setup and Configuration. What is far more bothering is scoping the output at Z shows only 1. Has anyone created a model for this analogue mux?

It is not possible to read or write more than one pin on the at the same time, because you can only select one pin at a time. Most Active Software Boards: You can get the datasheet from their website and then use the ‘New Component Wizard’ to create it.

Message 7 of Arduino on other Chips. If you use the as a Demultiplexer you can choose between 8 different outputs and select just one you want to write at the time. Sources for Electronic Parts. I created a very simple no attempt to model delays or capacitive loading model which I think ought to work, but it behaves slightly oddly.


If I have misunderstood please forgive me. Message 5 of Here it is with the model name corrected and also with a correction to the Mux Input selection switches bit, which I initially hoped was what my problem was, but it is still not working. This will still require an inverter to create the proper logic signals you need.

Arduino Playground –

Futhermore, the is able to work with analog values; in the case of the Arduino, you are able to use the analog inputs with a voltage between V and route them to an Analog-In Pin on your Arduino. Message 2 of Message 10 of The main differences are.

Could you please clarify which one it actually is? So that clearly doesn’t fly as an option: Message 1 of Here’s an alternative idea that might hd4051.

If you use the as a Multiplexer: Message 8 of You can choose between 8 different inputs and h4c051 just one you want to read at the time. Another idea would be to use the default model. Message 4 of How can I debug this please? Kittmaster’s Component Database http: But you can read and write to the pins quite fast. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.
