It uses a 4-wire serial interface. ## Supply current and thermal margin The 330 mA supply current is the total chip draw with all segments lit at full drive. The -40°C to 85°C operating range covers industrial environments. ## Sourcing and availability We source the MAX7221ENG+ through independent distribution channels. This part is quoted to order with no minimum commitment.","metaTitle":"MAX7221ENG+ LED Driver, 7 Segment 8 Digit, 24-DIP, Active","metaDescription":"MAX7221ENG+ LED driver IC from Analog Devices.

Both use the same 24-DIP footprint, so you can swap them without board layout changes. The key difference is that the MAX7221 includes an additional 8x8 static RAM and a more flexible serial interface that supports daisy-chaining multiple devices."},{"question":"Can MAX7221ENG+ drive common cathode or common anode LEDs?","answer":"The MAX7221ENG+ is designed for common-cathode LED displays. The segment drivers source current, and the digit drivers sink current. Common-anode displays require an external transistor array or a different driver part."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX7221ENG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX7221ENG when reusing this data.
