TCA9544A: 2-channel I2C-bus master arbiter

TI does not make such a device.

The PCA9641 automatically detects which master is currently active. But if it is possible to change the board so that the switch is manually controlled with a GPIO signal, then you can use any general-purpose analog switch like the TS3A5223.

Hi Naizeng,

As Clemen's pointed out we do not have a device like the PCA9641.
