Description:
The MAX7221 is an integrated LED display driver IC designed by Maxim, capable of driving up to eight 7-segment numeric displays or 64 individual LEDs. It simplifies the process of controlling LED displays by reducing the number of microcontroller pins required through its SPI-compatible serial interface.
With built-in BCD decoding, brightness control, and multiplex scanning circuitry, the MAX7221 offers efficient LED driving with minimal external components. Packaged in a DIP24 through-hole format, it is ideal for prototyping, breadboards, and final PCB assembly. This pack of 3 ICs provides flexibility for multiple display projects or spare parts in development labs.
