Additional Details

The HDSP-2114S-24 communicates via a serial interface, which minimizes the number of pins required for connection to a microcontroller or other control device. The integrated CMOS IC handles the multiplexing and driving of the LEDs, simplifying the design process. The display characters are formed by selectively illuminating the dots within the 5x7 matrix. The serial interface typically uses a shift register approach to load the data for each character. The display is designed for easy readability, with a wide viewing angle and high brightness. It operates on a 5V power supply. The -24 likely refers to a specific brightness or intensity level. Consult the datasheet for detailed electrical characteristics, timing diagrams for the serial interface, character codes, and physical dimensions. The device is a popular choice for applications requiring a compact and easy-to-use alphanumeric display.
