Is there a level conversion chip that supports I2C and SPI, and the communication clock for SPI level conversion is not distorted above 25MHz?

Hi Fang,

Note that SPI is for push-pull fixed direction applications while I2C is for open-drain bidirectional applications.

Please see the TXU or the AXC family (TXU0304 / SN74AXC4T774) for SPI and the LSF or the TXS family (LSF0102 / TXS0102) for I2C similar to Voltage Translation Application Quick Reference, thanks.

Best Regards,

Michael.
