Hi Ann,

I would read through this thread: https://e2e.ti.com/support/logic-group/logic/f/logic-forum/788450/sn74lvc244a-mdc-mdio-buffer-for-1-2v-operation

Specifically, the last response. I believe the translation team will be able to help you more.

Hey Ann,

MDIO signals are generally supported by open drain drivers, so I2C buffers are compatible. However, MDIO signals tend to support higher data rates also, which may be a limitation for I2C buffers.

Could you provide more information of the customer's application? What is the desired data rate/ operating VCCA/ VCCB? Is buffering truly required or just translation?

Here is a general list of I2C buffers that can be considered.

Regards,

Jack
