PCA9538DBR Frequently Asked Questions (FAQs)

  • The PCA9538DBR can support I2C bus frequencies up to 400 kHz, but it is recommended to operate at 100 kHz or lower for reliable operation.
  • The PCA9538DBR can be reset by pulling the RESET pin low for a minimum of 1 ms. This will reset the device to its default state.
  • The PCA9538DBR 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 PCA9538DBR 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 translator or level shifter for more reliable operation.
  • The PCA9538DBR can be configured for open-drain or push-pull output mode by writing to the Configuration Register (Register 0x03). Bit 0 of this register controls the output mode, with 0 being open-drain and 1 being push-pull.
