TCA9406: Any I2C level shift supports over 3.1MHz?

Hi Team,

Customer is asking if TI has any I2C level shift  that can support 3.1MHz clock freq?

Thanks!

    Hi Andrew,

    The only device we have from the I2C translator portfolio which could support that range would be the PCA9306. Figure 3 in the datasheet shows that the -3dB point for the device is around 250MHz. You'll need to size the pull up resistors correctly to support the rise times you need to maintain for those speeds.
