Part Number: TXS0108E-Q1
Other Parts Discussed in Thread: TXU0304-Q1

Hi Team,

I would like to use TXS0108E-Q1 for voltage conversion of 5V⇔3V on SPI communication of 400kbps.

Is there any problem should be considered?

Beat Regards,

This will work. Please note that the TXS has internal pull-up resistors and will not work with external pull-down resistors.

For fixed-direction signals, a translator like the TXU0304-Q1 would be a better solution.
