PCA9539PW Frequently Asked Questions (FAQs)

  • The PCA9539PW can support I2C bus frequencies up to 400 kHz.
  • To use an external pull-up resistor, connect the resistor between the SCL/SDA pins and the VCC pin. The recommended value is 1 kΩ to 10 kΩ.
  • The PCA9539PW can sink or source up to 25 mA per output pin.
  • The PCA9539PW can be reset by pulling the RESET pin low for at least 1 ms. This will reset the device to its default state.
  • No, the PCA9539PW is designed to operate with a 1.65V to 3.6V power supply. Using a 5V power supply may damage the device.
