TXB0104: VCCB = 5.85V

Part Number: TXB0104

I'm looking for a solution to translate between 3.3V and 5.85V.  Outside of old CD4K type devices that are too slow, I was thinking about using a TXB or TXS type device.  The driving logic is push-pull, so I'm leaning towards TXB. These translators are typically spec'd to have VCCB up to 5.5V , but the Absolute Max rating is 6.5V.  

Are there concerns about operating these translators with VCCB = 5.85V?

    We can't guarantee that the part will meet spec outside the recommended operating region.

    Can I ask why 5.85V? That's an oddly specific logic rail that isn't 5V. Is there some IC out there that only works at this odd voltage, or is your use case just very specific?

    Hey Mark,
    I'm going to go ahead and close this / mark it as resolved since I haven't heard back from you in several weeks. If you need any additional information, please just respond to this thread and I will be notified.
