PCA9538PW Frequently Asked Questions (FAQs)

  • The PCA9538PW 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 internal pull-up resistors must be disabled by setting the PUEN bit in the Configuration Register to 0.
  • The PCA9538PW can sink or source up to 25 mA per output pin.
  • The PCA9538PW 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 PCA9538PW is designed to operate with a power supply voltage of 1.65V to 3.6V. Operating the device with a 5V power supply may damage the device.
