TXU0102: SPI Level Shifter Part Recommendation

Part Number: TXU0102
Other Parts Discussed in Thread: SN74AXC4T774, , TXB0104, TXU0304, TXU0104, TXU0204

Hey team,

I am in search of a SPI level shifter IC that would translate 3.0V to 1.8V. It needs to be able to handle SPI speeds up to potentially 12MHz while being in a small package. 
Would you be able to help me figure out what would best fit with these requirements?

Upon first glance, the TXU0102 in X2SON packaging seems like a great choice but let me know if I'm missing something. I'm also seeing SN74AXC4T774 for direction-controlled, and TXB0104 for auto-direction. I don't know the specific application (only received the blurb above) so I'll likely just send three choices from each sub-family his way. Please let me know if I missed something!

Thanks!

    Hi Marco,

    Please note that, I wouldn't recommend auto bi directional devices for applications that are not auto bidirectional.

    For fixed directional SPI applications, the TXU (TXU0304 / TXU0204 / TXU0104 for 4 channels) would be a suitable recommendation. Direction controlled AXC family also works well, thanks.

    Best Regards,

    Michael.
