EE.SE has quite a few questions asking to identify unknown parts, usually ICs. These are quite rare, so I cannot say I'm annoyed by them. Yet every time I see one, I come to to think whether they are useful to anyone besides the OP.
In fact, these questions are essentially duplicates in terms of information one could reuse:
- identify the package.
- google for the package name plus the markings, try adding the word datasheet to the query.
- try using IC markings search engines.
- identify the IC manufacturer by logo to refine the search, or search on manufacturer's website.
Should we post these instructions somewhere and close "identify this part" questions which show no evidence of the OP performing a basic search?
