PCF8574PWR Frequently Asked Questions (FAQs)

  • The PCF8574PWR can source up to 20mA and sink up to 24mA per I/O pin.
  • The PCF8574PWR is configured for I2C communication by connecting the SCL pin to the I2C clock line and the SDA pin to the I2C data line. The device address is set by the A0, A1, and A2 pins.
  • The INT pin is an open-drain output that is asserted low when an input pin changes state. It can be used to interrupt a microcontroller to signal that an input has changed.
  • Yes, the PCF8574PWR can be used as a level translator. It can translate signals from a lower voltage domain (e.g. 1.8V) to a higher voltage domain (e.g. 5V) or vice versa.
  • The PCF8574PWR can handle I2C clock frequencies up to 400 kHz.
