LSF0108: Best option for QSPI voltage translation

Part Number: LSF0108

Hi,

I am considering using the LSF0108RKS for QSPI transaction, but I want to know if this is the best option.

The QSPI interface will be between a 3.3V controller and 1.8V SPI flash.

The way QSPI will operate is that first, the controller will own the 4 data lines (IO[3:0]) for the first byte. Following the first byte, the slave will have control of the 4 data lines. We will be operating this bus at 25MHz.

Is this the best device to use for this application (and will it work)? Are there any better options available?

Any help would be much appreciated!

Regards,
Prathik
