Overview
Expand your microcontroller's I/O capability with the PCF8574P 16-DIP I/O Expander IC. Designed for easy integration into digital electronics projects, this compact 16-pin IC provides 8 additional I/O lines through the I2C bus.
The PCF8574P is particularly useful when a microcontroller does not have enough GPIO pins for all connected peripherals. Instead of dedicating multiple controller pins to LEDs, buttons, switches, displays, or other digital devices, the PCF8574P lets you communicate with the expansion IC using the I2C SDA and SCL lines.
Its 16-DIP package makes it convenient for breadboard prototyping, PCB development, educational electronics, automation systems, and DIY projects. It is also widely useful for adding GPIO capability to microcontroller-based LCD and keypad interfaces.

Product Technical Information
Technical Details
The PCF8574P 16-DIP 8-Bit I/O Expander IC is designed to provide additional digital input/output capability for microcontrollers and embedded systems. It communicates using a two-wire I2C interface, allowing eight additional I/O lines to be controlled without consuming a large number of GPIO pins on the host controller.
The eight I/O ports are quasi-bidirectional, allowing them to be used for a variety of digital input and output functions. This makes the PCF8574P useful for connecting buttons, switches, LEDs, LCD modules, keypads, and other digital peripherals.
The 16-pin DIP package is well suited for breadboards and through-hole PCB assembly, making it a convenient choice for prototyping and educational electronics projects.
