PCA9555PWG4 Frequently Asked Questions (FAQs)

  • The PCA9555PWG4 can support I2C bus frequencies up to 400 kHz, but it is recommended to operate at 100 kHz or lower for reliable operation.
  • The PCA9555PWG4 is configured to operate in 16-bit mode by default. To operate in 8-bit mode, the A0 and A1 pins must be tied to VCC or GND to select the desired mode.
  • The PCA9555PWG4 can sink or source up to 25 mA of current on each I/O pin, but it is recommended to limit the current to 10 mA or less to ensure reliable operation.
  • The PCA9555PWG4 can be reset to its default state by pulling the RESET pin low for at least 1 ms. This will reset all registers and I/O pins to their default state.
  • Yes, the PCA9555PWG4 can be used as a level translator between different voltage domains, but it is limited to translating between 1.8 V, 2.5 V, 3.3 V, and 5 V domains.
