Other Parts Discussed in Thread: TSC2046E

I am wondering where I find obsolescence info for this part, if I include this part in my design, when would I expect it to be discontinued by the manufacturer. Where can I find this info for other TI parts. Digikey does not have this info.

    Steven,

    For new designs, we recommend TSC2046E with extended ESD protection.

    Customer: If you want to look up my company name on my info you can, I'd prefer not to post it here for privacy reasons. If you want I can send you the info if you give me some contact info.

    Application: Instrumentation Touch Screen

    Industry: Scientific Instrumentation

    One problem we have had in the past is parts go obsolete and we don't know when. This is a problem because on  some of our products we make a design with a part that is currently in production, then later on the company pulls the part (this is why were looking for a part right now). Then we have to spend time and money to come up with a replacement board, this happens more often then you would think all it takes is one part that doesn't have a drop in replacement. I need to know how long the parts will remain on the shelf Linear Tech offers a guarantee (something like 5 years after the part is made obsolete, you can still order it). I don't expect this, but I do expect to know when the part will be made obsolete so I can decide if I want to include the part in the design or not.
