PCA9534ADW Frequently Asked Questions (FAQ)

  • The PCA9534ADW can support I2C bus frequencies up to 400 kHz, but it is recommended to operate at 100 kHz or lower for reliable operation.

  • The PCA9534ADW can be reset by pulling the RESET pin low for at least 1 ms. This will reset the device to its default state.

  • The PCA9534ADW can sink or source up to 25 mA on each output pin, but it is recommended to limit the current to 10 mA or less to ensure reliable operation.

  • Yes, the PCA9534ADW can be used as a level translator between 1.8 V and 5 V logic levels. However, it is recommended to use an external voltage regulator to ensure stable operation.

  • The PCA9534ADW can be configured for open-drain or push-pull output mode by writing to the Output Mode Register (OMR). A value of 0x00 sets the output to open-drain mode, while a value of 0x01 sets the output to push-pull mode.
