TCA9548A: PCA9547 replacement?

Part Number: TCA9548A


Hi Team,

I see TCA9548A is P2P with PCA9547, but the register table is different. Is there any TI device that are functional and P2P replacement with PCA9547? Thanks.

Best regards,

Andy Chu

  • Hey Andy,

    PCA9547 is a I2C MUX in which only one channel can be enabled at a time. The only I2C MUX we have in our portfolio is the 9544 series which is not an 8 channel MUX like the competitor. So in terms of same register setting, we do not have a direction replacement which does not require a software change. The closest thing we have is TCA9548A which could perform the same operations but the customer would need to modify software.

    Thanks,
