Hi All,

Whats the default pin state of the IOs in TCA9534 after power up before any I2C configuration?

  • Hello Bala,

    Please refer to Table 3 on page 19 of the current datasheet for the default values of each register. If you have any further questions just let us know.

  • Hey Bala,

    The datasheet provides this information on Table 3:

    Because Configuration is set to 0xFF, the IO ports are HI-Z inputs. Input port state is undefined because there are no pull ups/pull downs internally to reference them.
