ISO3086T: 3.3V supply on the bus side

Part Number: ISO3086T
Other Parts Discussed in Thread: ISO35T


I have a customer that migrated away from ADM2487E to ISO3086T. They didn’t realize it is only 5V supply on the bus side.  

They are currently giving it 3.3V.  They haven’t had any issues. What would happen if they run the part on a 3.3V bus supply.  Trying to determine what the failure point would be, if any, so we can decide how to proceed regarding both devices already in the field and future manufacturing.


  • Hi Lindsey,

    Thank you for reaching out to us!

    We only characterized the VCC2 of ISO3086T at 5V, and we don't have data to comment on its performance at 3.3V.

    Will your customer consider ISO35T? It is P2P to ISO3086T, and its VCC2 supports 3.3V.
