Hi Brian,

Unfortunately, we do not have a direct replacement for this device. We do have a portfolio of I2C switches available.

For example, the TCA9548A could be used as it has the 50ns deglitch filter so it will ignore I3C signals once the bus enters I3C mode. TCA9548A also does not clock stretch (requirement for it to be allowed on I3C bus so this is good). You will need to disable TCA9548A's channels when you decide to enter I3C mode with this device

Here are some helpful posts about using our I2C switches for I3C applications:
