Hi Deepak_,
About TXS108 IC, as seen on TI's official website: firstly, the TXS010x series level converter devices can be used for I2C and SPI applications. However, due to their weak DC drive capability (20uA), it is not recommended to use such devices if the PCB wiring is relatively long and requires a certain drive capability. Additionally, it is not recommended to use internal pull-up resistors as external pull-up resistors have better driving capabilities. We suggest that you set the power supply voltage of both the host MCU platform and BHI360 to 1.8V, so that you can directly connect the host MCU and BHI360 without using level conversion.
