Other Parts Discussed in Thread: TCA9517
Tool/software:
Hello,
I have a 5V micro-controller and only one I2C bus, and a remote 3.3V sensor, between them about 0.85m long wires, so I'd like to add I2C buffer to isolate sensor from other I2C slaves on the board and level down translation needed. Is it OK to implement 5V I2C master -> TCA9517 B_5V - A_5V -> 0.85m wires -> TCA9517A B_5V-A_3.3V -> 3.3V sensor? With this implementation, I follow all the design requirements of TCA9517A, but still want to make sure this design is OK, data sheet doesn't give an example of series application using B-A to B-A, thanks.
Regards,
Dawei Ma
