TS3A44159: SPI Mux

Hi Patrick,

The SN74CB3Q3257 and the TS3A44159 can both be used for SPI bus depending on you voltage supply. Another great option is to use the newly released TMUX1574, which calls out SPI bus multiplexing on the front page and in the applications section.

The TMUX1574 has a wide operating voltage and 1.8V compatible control logic which makes it suitable for many applicatons. What are you multiplexing the SPI lines between in your system?

Patrick,

You can use the button on the Ti.com switch selection tool to find devices that support SPI signals.

Thank you,

Adam
