I found some stock components in my office warehouse. Unfortunately no one knows the type and function. Looking at the logo, it appears that he was produced by Texas Instrument. However I was browsing on the TI web, not finding any meaningful hints. I tried googling, also still find the answer. Has anyone here used this part? I need the datasheet. thanks.

I tried to browse the link you provided, but I still have not luck. there is no information (datasheet) for the IC. Thanks for trying to help me.

 

Please post the photo or whatever is in the link at #1 here.

It looks like a custom part number to me. Could it be a custom chip designed for your company?

 

The line at the top looks like a date (probably 2004, supported by the underlined 04 in the second line). 44K seems to me the marking most likely to have something to do with a part number.

Unless your company is large and purchased large volumes of components, I doubt if it is a custom part. If it is large, then it really should have documentation somewhere.

Send the photo to TI customer support.

I can't explain it and I don't know what the chip is, but I don't think 0402092 is a date code and 44K is the part code.

There are many references to a TI TSSOP 14 chip with SN0402092/0402092 like here http://www.ic2ic.com/search.jsp?sSearchWord=SN0402092&prefix=S or here https://www.jotrin.com/product/list?keyword=SN0402092#details

I can't find a data sheet and the TI identifier site http://www.ti.com/packaging/docs/partlookup.tsp does not recognize it. Yeah, I would like to hear what TI would say.
