Hi team,

I'd like to check with you that if we want to achieve SPI PCB inter-board communication and enhance SPI anti-interference ability, what is the cheapest solution? Thanks!

Hi Jiawei,

What is the I/O voltage?

Hi Dylan Hubbard,

The I/O voltage is 5V.

Hello Jiawei,

For 5V, the SN74AXC4T774 will not work because it can only support up to 3.6V.

The other question would be how many signals do you have an what is their directionality?

If its a typical SPI interface, with 3 in one direction and 1 in the other, then we have a great solution for this application which also supports 5V.
