TXU0304: SPI Driver with multiple Slave GPIO

Part Number: TXU0304

Tool/software:

Hi,

I am looking for a SPI level shifter however I need one which can handle multiple devices.

Ideally would be TXU0304 but with 6 GPIO however I noticed that you don't offer this.

Which alternative is closest to the one mentioned above? LSF0108?

Hi Revky,

You may also use the TXV family for GPIO with more channels. See TXV0106 or TXV0108. See https://www.ti.com/lit/po/scea118/scea118.pdf?ts=1721834839275&ref_url=https%253A%252F%252Fwww.google.com%252F for additional GPIO recommendations, thanks.

Best Regards,

Michael.

Okay but that means I would need to use for example 2 x TXV0106 one for each direction. What I wanted was a one chip solution to have SDI/SDO/CLK + 3 CS pins either fixed or bidirectional

Use TXU0304 + TXU0102 (or TXU0104 + TXU0202), or 2× TXU0304 to simplify the BOM.

If you want a single chip, you have to use an unbuffered translator like the LSF0108 or TXS0108E.
