I/O Expanders Texas Instruments PCF8574RGTR Overview
The I/O Expanders Texas Instruments PCF8574RGTR is a highly efficient and versatile 8-bit I2C I/O expander designed to enhance the input/output capabilities of your microcontroller systems with minimal overhead and simplicity. Manufactured by Texas Instruments, this device uses a two-wire I2C interface, which makes it ideal for applications where pins on a microcontroller are limited. The PCF8574RGTR facilitates robust serial communication with various devices by providing additional I/O ports that are configurable either as inputs or outputs. This component is especially beneficial in applications requiring interface with multiple non-volatile memories, sensors, and other peripherals without demanding significant hardware complexity or additional space.
PCF8574RGTR Features
This compact 16-VQFN packaged I/O expander offers key features to enhance its utility and performance in various applications:
- 8-bit remote I/O expander for I2C-bus/SMBus applications
- Low standby current consumption of 10 µA max, ideal for power-sensitive applications
- Operating voltage range from 2.5V to 6V, supporting a wide array of devices
- Interrupt output, providing a direct, hardware-driven notification to the host controller upon input changes
- Three hardware address pins to configure up to eight devices on the same bus, allowing for significant expansion of I/O points without additional pins
PCF8574RGTR Applications
- Smart Home Systems: Enhances connectivity by adding more I/O ports to control devices like lighting, security alarms, and thermostats.
- Industrial Automation: Facilitates the management of sensor data integration into control systems with minimal input/output points.
- Consumer Electronics: Used in devices requiring additional buttons or indicators such as media players, gaming consoles, and TVs.
- Mobile and Wearable Devices: Supports the development of compact, feature-rich wearable tech by providing additional I/O without significant power consumption.
- Robotics: Enables efficient communication and control between the central microcontroller and various sensors, actuators, or other peripheral devices in robotic systems.
