SN74HC04: new products don't work

Part Number: SN74HC04


We have issue with SN74HC04 part, the component with marking HC04 15K G4 ACRF , this component simply does not work, we do not have the ability to perform a more detailed analysis. Whether this hexa inverter is not working at all, or there is a timing issue, we can't say that. Products with marking HC04 9CK G4 CLHV are working perfectly. Please investigate what could be the reason, I need your feedback to return not working parts.

  • Hello,

    I will need to know more information to find out what the issue is.

    If, as you say, you cannot do an analysis, then I cannot help. This forum is for technical assistance, and I cannot test your equipment from here. I can only provide recommendations on what you need to check.

    The first thing I would need to see is the schematic -- how is the device being used?


    If you do not want to work with me on this, please mark this thread as "Resolved" and submit a return request through your distributor.
