SN74LVC2G07: no output fail condition

Part Number: SN74LVC2G07
Other Parts Discussed in Thread: 5-8-LOGIC-EVM

hi Team,

we have a SN74LVC2G07 return that has no output signal when input is applied

it's observed that the resistance measured from the Vcc to Vss is 6k, while the resistance measurement from a good IC is 21K~22K

may we check with the application, that what might the causing the failure? for example the input pins exceeds the abs max ratings -0.5V~6.5V 

or current, temperature?

Thanks very much 

  • Hi John,

    Could I see a picture of the schematic you're using to test the device?

    Could I also have some scope screenshots for your inputs to the device and outputs from it?

    Finally, was a Failure Analysis request submitted for this part, and if so, what was the FA number?

    Thanks!

  • hi Chad

    appreciate the feedback.

    i was able to apply for a TI 5-8-LOGIC-EVM to test the NG IC and a GOOD IC

    measurements below, seems the NG IC 2Y output is not funcitoning

    VCC 5V

    NG IC

    1A 0V -> 1Y 0V

    1A 5V -> 1Y 5V

    2A 0V -> 2Y 0V

    2A 5V -> 2Y 0.04V

    Good IC

    NG IC

    1A 0V -> 1Y 0V

    1A 5V -> 1Y 5V

    2A 0V -> 2Y 0V

    2A 5V -> 2Y 5V

    Thanks
