TCA9543A: Replace LTC4316IMS

Hi Kevin,

To my knowledge there is no such device from TI.  For applications involving communication with multiple slave nodes sharing a common address, I would recommend using an I2C switch or multiplexer to enable communication to one slave at a time.  You can browse the products we have available for this here:

Or, depending on whether or not the slaves latch their address configuration you might be able to implement "dynamic addressing," for example by using a GPIO expander to control the address lines.  You can read more about that here:

Our portfolio of GPIO expanders can be found here:

Please let me know if you have any questions or feedback.

Regards,
Max
