PCF8574AP Frequently Asked Questions (FAQs)

  • The PCF8574AP can support I2C bus frequencies up to 400 kHz.
  • The PCF8574AP can be reset by pulling the RESET pin low for at least 1 ms. This will reset the device to its power-on state.
  • The PCF8574AP can sink or source up to 25 mA on each I/O pin.
  • Yes, the PCF8574AP can be used as an input port expander. The device can be configured to read the state of the input pins and transmit the data to the I2C bus.
  • To configure the PCF8574AP as an output port expander, the device must be written to in the output mode. The output values are latched and remain valid until the next write operation.
