Hi Bricolo,
These are only available to IEEE members. Thanks for the links though.

[Bricolo]

that's strange, I can download them even without being logged in, and with no cookie

anyway, I didn't know, but I don't want to take the responsability to attach the files

Don't open it.
Save link target ( or something like that ) works

Yesterday I received a standard TDA1541A. This one was obtained from an official distributor but it looks different from the ones I have/had.

Remarkable is that it has no printing on it but it has laser engraved marks. It has also "taiwan" written on it.

Now comes the interesting part: it has a datecode of 2004 ! I thought I just let you all know. I have no explanation for it but it seems the chip has been produced way after it was declared obsolete. However, this is speculation of course. I can not think of another explanation since it was sold by a Philips distributor so it won't be a fake or rebranded chip.

 

[Bricolo]

and is the chip working?

I'll try to get some information about recent batches of production of the 1541

 

[jean-paul]

I am too busy now to try it but I will try it of course. This will not be soon though.

 

[Bricolo]

no problem, we're all busy

could you post a picture?
