  • PCA9306: PCA9306 3.3V to 5V I2C level translator not working

    Part Number: PCA9306 Hi TI Team, We are using the part PCA9306DCUR to level translate from 3.3V to 5V I2C interface. The flow is as shown below. We are able to read the I2C address of the fan controller device but when we try to read the data we are not…

  • PCA9306: Resistance selection

    Resolved
    Part Number: PCA9306 Hi Team, As for the datasheet "8.1.2 correct device set up", there are setup examples that connect EN and Vref2 terminals to Vcc2 via 200kΩ resistor, but is there a tolerance range of the 200kΩ? (e.g. recommended for use between…
