I'm looking for an IC with the markings 22CEHJK04 F38 and I couldn't find it on your site. Do you know where I could purchase this part or of a replacement for this part?
Please provide more information about this part. How many pins? What package type? How do you know this is a Texas Instruments device? A picture would be useful.
Also please become familiar with the Part Marking Tool. From the Overview page of TI.com ( http://www.ti.com/applications/overview.html ), click the Quality & reliability tab, find the Park marking lookup link. On this page ( http://www.ti.com/packaging/docs/partlookup.tsp ), enter the Part Marking; for what you provided, the F38 marking produced a list of possible devices.
Scroll down to the end of the list where only the F38 marking is listed, then this is likely an SN74F38 version. If you verify that this is indeed the device, you can purchase these from the TI Store: https://www.ti.com/store/ti/en/ .
