Hi Jimmy,

The TMUX1574 is one of our recommended multiplexers for SPI switching and appears to be a good fit for the application based off the block diagram provided.

Please refer to our FAQ on the topic for more information: [FAQ] What Analog Switch / Multiplexer Should I use for SPI Applications (3/4 Wire SPI, QSPI, or OSPI) ?

Thanks,
Tyler
