Hi team,

Customer would like to know if PCA9515A work as SMBUS buffer? The pull up voltage will be 3.3V to 3.3V. Is there any reference circuit?

Hi Oliver,

This device can work as a buffer, but I would highly recommend moving to a newer device such as TCA9517/A or TCA9617B as these use the most up-to-date technology and can also level shift.

Regards,

Tyler
