Whither 4053_tercio.asy

 

The analog switch library "SwitchAna.Lib" makes reference to various symbols (e.g.  "4053_tercio.asy") and phrases like "The model needs two params: Vcc & Vel see the circuit example..".  Where might I find these?

It's difficult to trace back in time, 7 years later.  But the library file "SwitchAna.Lib" was uploaded and mentioned in this thread:
Unfortunately, that .Lib file was the only thing uploaded then.  Bordodynov was the uploader, and he is still occasionally active in this group so maybe he can fill in the gaps.
 
Regarding the missing parameters, just define them yourself, maybe something like this:
    .param Vcc=10   (use your actual voltage)
    .param Vel=1   (guessing that Vel is a relative speed setting where 1 = nominal)
 
For the LTspice symbol, I suggest drawing it yourself.  So, for the 4053, draw the symbol for a CD4053, see how the pins line up with the .SUBCKT definition (".Subckt 4053_tercia I inh xio yio xoy"), and you might be good to go.
 
That .Lib file apparently came from somewhere else, and the one .Lib file might be the only thing that made it into this group's Files.  I suggest carefully reading the thread above about the CD4053 to see if you can find any clues.  Otherwise, wait to hear from Bordodynov himself.

A much older version of "SwitchAna.Lib" was also mentioned in this 2008 message thread:
https://groups.io/g/LTspice/topic/50176653 ("X046 Lib & Cmos Switchs Libs")
but it appears they did not successfully upload the library containing that and other files.
 
It looks like they may have uploaded the whole thing to a different Yahoo!Group which does not exist anymore.  There may be some hope of finding it again but don't hold your breath.  (At one time I downloaded the files from the extinct LTspiceDocs group, but I might not be able to find them today.)
 
That 2008 message thread also mentions "LTspicePlus", which I think was another large collection of user-contributed models and files to use with LTspice.  I think you can find LTspicePlus at the LTwiki website, here:
Scroll down to "New Updated Version".
 
I think LTspicePlus downloads as a self-extraction .exe file - so it is really a .zip file with self-unzipping code included.  Maybe that librarry contains all the missing information you seek.

John & Andy,
I found the files in my offline LTspice storage location.
Files are uploaded as 4053_tercio.zip.
I have no idea if the files are current with the latest Bordodynov library.
You will simply need to try the example and see if it works.

Thanks, Mike.
 
I don't know if it matters (to John W), but your uploaded .zip file is missing the symbols "1To2.asy" and "switchana.asy".

I can live without them, and I'm sure Andy will provide all the help you need.

Sorry!  That was the other John W (Waugaman).

Story of my life! That's why I usually use 'JMW' rather than 'JW', but at one time there were at least three people called John Michael Woodgate (only very distantly related, if at all) in Britain.

Andy,
I had to do a deeper search in my archive, but found them.
I uploaded a newer zip file with the missing asy files.

Hello John W.
I have uploaded the complete Robertugo/SwitchAna files from my personal archive.
It appears to contain all that is needed for the 4051, 52 and 53 parts.
I hope this helps.
 
All for now

Except the model and symbol for CD4024 that are needed to run most of the circuits!
 

"By Jove, I think he's got it!"
Many thanks!  
John (Waugaman, that is)
 
 

I located the missing pieces.
All of the examples work now.
Try again, please.

Hi
 
I've uploaded CD4051B, CD4052B and CD4053B models.
