MAX6967AEE+T - Maxim Integrated

The MAX6967AEE+T is a versatile, 16-port, serial-interfaced peripheral from Maxim Integrated, designed to add input/output (I/O) expansion to microcontroller-based systems. This device is particularly suitable for applications requiring multiple I/O lines, such as LED drivers, display controllers, and general-purpose I/O extensions.

Key Features

• Serial Interface: The device features a SPI/QSPI/MICROWIRE-compatible serial interface, allowing for easy integration into a wide range of microcontroller architectures.
• Output Drive Capability: Each of the 16 ports can sink up to 50mA, making the MAX6967AEE+T ideal for driving LEDs or other low-power output devices.
• Input Functionality: The ports can also be configured as inputs, providing flexibility for sensing external signals or for interfacing with switches and sensors.
• Flexible Operation: The device operates from a 2.5V to 5.5V supply voltage, accommodating various logic levels and making it suitable for both 3.3V and 5V systems.
• Integrated Features: Built-in features include open-drain output stage, transition detection on any I/O pin for interrupt generation, and internal pull-up resistors on inputs, which simplify the circuit design and reduce external component count.
• Package: The MAX6967AEE+T comes in a compact 16-pin QSOP package, which minimizes the footprint on the PCB and is ideal for space-constrained applications.
