PCF8574ATD Frequently Asked Questions (FAQs)

  • The PCF8574ATD can handle I2C bus frequencies up to 400 kHz, but it's recommended to use a maximum frequency of 100 kHz for reliable operation.
  • The PCF8574ATD can be reset by pulling the SCL line low for at least 10 ms. This will reset the device and clear all registers.
  • The PCF8574ATD can source or sink up to 25 mA per I/O pin, but the total current should not exceed 100 mA.
  • Yes, the PCF8574ATD can be used as a level shifter, but it's not recommended as it's not designed for this purpose. The device is intended for I/O expansion and not for level shifting.
  • The PCF8574ATD generates an interrupt when an input pin changes state. The interrupt can be handled by reading the interrupt status register and clearing the interrupt flag.
