SN74CBTLV3125: could SN74CBT3125 replace SN74CBTLV3125?

Part Number: SN74CBTLV3125
Other Parts Discussed in Thread: SN74CBT3125,

Hello expert,

Customer is facing supply issue on SN74CBTLV3125DBQR. We would like to know if SN74CBT3125 could replace SN74CBTLV3125. It seems like VCC is a spec we need to discuss. Could SN74CBT3125 accept 5V for VCC? Thanks a lot!

Best regards,

Ann Lien

  • Hi Ann,

    I would like you to clarify which part you are looking to replace. The SN74CBTLV3125 which is the one you are saying you need to replace supports only up to 3.3V, however, looks like you are indicating your application is using a 5V supply? The SN74CBT3125 can work up to 5V.

    So essentially, if you are looking to replace the SN74CBTLV3125 with the SN74CBT3125, then that will work perfectly fine. However, if you are trying to replace the SN74CBT3125 with the SN74CBTLV3125, then that will not work as the SN74CBTLV3125 has a lower supply voltage only up to 3.3V.


  • Hello Bryan,

    customer is using 3.3V system right now and we would like to make sure if SN74CBT3125 could support 3.3VCC. Thanks!

    Best regards,
