Apr 28, 2025 · This page provides the PCF8574P pinout diagram, pin configuration, pin descripton, schematic, and functional block diagram. See the pinout diagram and ordering information. The Serial LCD backpack built on PCF8574 IC uses the I2C bus to convert the parallel interface to a serial one. [2] Using a additional chip type PCF8574A, you can double the number of chips on the I2C bus as its address starts from 0x38. PCF8574 GPIO Extender - With Arduino and NodeMCU: In my last tutorial, I talked about the TCA9548A MUX which can be used to add at the max of 64 I2C or I²C sensors to your Arduino/ESP8266/ESP32. Ideal for engineers working on microcontroller-based systems. It can be connected to a processor like Arduino to control more devices using fewer pins.
