PCAL9538ABSHP Frequently Asked Questions (FAQs)

  • The maximum current that can be sourced or sunk by each I/O pin is 25mA.
  • The PCAL9538A can be configured as an input or output by writing to the configuration register (address 0x06). A '1' in the configuration register sets the corresponding pin as an input, while a '0' sets it as an output.
  • The internal pull-up resistors on the I/O pins are used to pull the pins high when they are configured as inputs. This helps to prevent the pins from floating and reduces power consumption.
  • The PCAL9538A can be reset by pulling the RESET pin low for at least 1ms. This resets the device to its default state.
  • The PCAL9538A can operate at I2C bus frequencies up to 400 kHz.
