Hi Gary,

Please help see section 1 of Voltage Translation Application Quick Reference, with TXU0304 as an example for SPI, thanks.

Hello Michael,

Thank you for the suggestion. So, TXS0108EPWR cannot be used for SPI?

Hi Gary,

TXS can be used, but not the most suitable. Due to limitations such as the datasheet's section 9.3.3 i.e fixed directional devices such as TXU are best recommended for fixed directional signals such as SPI.

Hence, if the datasheet's considerations are of no concerns, then it will work just fine, thanks.

Best Regards,

Michael.
