It integrates a BCD code-B decoder, multiplex scan circuitry, segment and digit drivers, and a shutdown mode. The 4-wire serial interface (data in, data out, load, clock) daisy-chains cleanly for multi-digit panels beyond 8 digits. The 24-DIP through-hole package suits prototype builds, retrofits on existing PCBs, and environments where socketed replacement is preferred over soldered SMD. ## Temperature grade and environment Rated 0°C to 70°C — commercial temperature grade. This covers indoor bench equipment, point-of-sale displays, instrumentation panels, and consumer appliances. Not specified for industrial or automotive under-hood environments; if the panel sits in an unconditioned factory bay or vehicle cabin, look at the industrial-temperature variant of this family. ## Lifecycle and sourcing That means it remains a current catalog item — no last-time-buy notice, no end-of-life risk for new designs.","metaTitle":"MAX7221CNG+ LED Driver, 8-Digit 7-Segment, 24-DIP","metaDescription":"MAX7221CNG+ LED display driver from Analog Devices drives 8 digits of 7-segment LED with 4-wire serial interface.

The key difference is the MAX7221 adds a 4-wire serial interface that is SPI-compatible, while the MAX7219 uses a slightly different serial timing. For most applications they are interchangeable, but the MAX7221 is the recommended choice for new designs due to its improved noise immunity."},{"question":"What is the MAX7221CNG+ used for?","answer":"It drives up to 8 digits of 7-segment LED displays or 64 individual LEDs in bar-graph mode. Typical uses include numeric readouts in panel meters, point-of-sale displays, instrumentation front panels, and alphanumeric message boards."},{"question":"Does MAX7221CNG+ work with 5V logic?","answer":"Yes, the supply range is 4V to 5.5V, so a standard 5V logic rail powers the device directly. The 4-wire serial inputs are 5V-logic compatible."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX7221CNG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX7221CNG when reusing this data.
