PCF8574T Frequently Asked Questions (FAQs)

  • The PCF8574T can support I2C bus frequencies up to 400 kHz, but it's recommended to operate at 100 kHz for reliable operation.
  • The PCF8574T can be reset by pulling the SCL line low for at least 10 ms. This will reset the device and clear all registers.
  • The PCF8574T can sink or source up to 25 mA per I/O pin, but the total current should not exceed 100 mA.
  • Yes, the PCF8574T can be used as an input expander. It can read the state of the input pins and transmit the data to the I2C bus.
  • You can address multiple PCF8574T devices on the same I2C bus by connecting the A0, A1, and A2 pins to VCC or GND to set the device address.
