Hello Syed,

Just to clarify, are you asking about the TCA6408A or TCA9548A?

The TCA6408A is an I2C IO expander while the TCA9548A is an 8-channel I2C switch.

Regards,

Josh

Hi Joshua,

Sorry I'm asking about the I2C switch TCA9548. Typing mistake.

Hello Syed,

Thanks for confirming.

The TCA9548A is supported by another team so let me transfer your question to them.
