Hi,
Could you tell me the newer recommendation device against PCA9515ADR?
BR,
Taku
The web site recommends the PCA9515B, but it is not available in the SOIC package.
The PCA9515x has a static voltage offset on both sides. Newer devices like the TCA9517(A) or TCA9509 have an offset only on one side, which is usually preferred (but it does not make a difference in existing circuits that already work with the PCA9515A). The TCA9800/1/2/3 uses a current source instead of a voltage offset, which canresult in better signal quality, but you must not use pull-up resistors on the B side.
Hi Taku,
Please let me know if you have any more questions. Clemens provided a good answer.

Tyler
