PCA9557DT Frequently Asked Questions (FAQs)

  • The PCA9557DT can support I2C bus frequencies up to 400 kHz.
  • The PCA9557DT can be configured for 8-bit or 16-bit port expansion by setting the A0 and A1 address pins. For 8-bit expansion, tie A0 and A1 to GND, and for 16-bit expansion, tie A0 to VCC and A1 to GND.
  • The PCA9557DT can sink or source up to 25 mA per output.
  • The PCA9557DT can be reset by pulling the RESET pin low for at least 1 ms.
  • The PCA9557DT outputs are in a high-impedance state (tri-stated) after power-on, and the internal pull-up resistors are disabled.
