The MAX6816EUS+T is a low-voltage, 8-channel I/O port expander with LED driver manufactured by Maxim Integrated. It serves as a versatile solution for expanding the number of input/output (I/O) ports available on microcontrollers or other digital devices. Additionally, it includes integrated LED drivers, making it suitable for applications requiring status indication through LEDs.

Key Features:

  • 8-Channel I/O Expansion: Provides 8 additional I/O channels for interfacing with external devices or peripherals, expanding the capabilities of microcontrollers or digital systems.

  • Low Voltage Operation: Designed for low-voltage operation, ensuring compatibility with modern microcontroller systems operating at low supply voltages.

  • Integrated LED Drivers: Features integrated LED drivers for controlling LEDs connected to the device, enabling status indication or visual feedback in the application.

  • High Output Drive Capability: Offers high output drive capability, allowing the device to drive external loads such as LEDs, relays, or digital inputs with ease.

  • Cascadable Operation: Supports cascading multiple devices for expanding the number of I/O channels further, enabling scalability in larger systems.

  • Serial Interface: Communicates with the host microcontroller or digital system via a serial interface (e.g., I2C or SPI), providing a simple and efficient means of control and configuration.

  • Flexible Configuration: Allows flexible configuration of each I/O channel as either an input or output, providing versatility in adapting to different application requirements.

  • Compact Package: Packaged in a small and space-saving microMAX package, offering ease of integration into compact PCB (Printed Circuit Board) designs.


  • Embedded Systems: Used in embedded systems, microcontroller-based projects, and IoT (Internet of Things) devices for expanding the number of available I/O ports.

  • Industrial Control: Integrated into industrial control systems, automation equipment, and PLCs (Programmable Logic Controllers) for interfacing with sensors, actuators, and other peripherals.

  • Instrumentation: Deployed in instrumentation and measurement systems for controlling relays, switches, or sensors and providing status indication through LEDs.

  • Consumer Electronics: Utilized in consumer electronics products such as home automation devices, smart appliances, and digital signage for I/O expansion and LED control.

  • Wearable Devices: Integrated into wearable devices, fitness trackers, and smartwatches for interfacing with external sensors, displays, and user inputs.

  • Automotive Electronics: Used in automotive electronics applications such as dashboard controls, infotainment systems, and automotive lighting for I/O expansion and LED control.

  • Security Systems: Deployed in security and surveillance systems, access control panels, and alarm systems for interfacing with sensors, switches, and indicators.

  • Medical Devices: Integrated into medical devices and healthcare equipment for expanding I/O capabilities and controlling status indicators or alarm signals.
