It accepts data via a 4-wire serial interface (SPI-compatible) and handles the multiplexing, current regulation, and BCD decoding internally — offloading the host microcontroller from display refresh tasks. Typical applications include panel meters, point-of-sale terminals, instrumentation front panels, and any numeric display in commercial equipment where a clean serial link simplifies the board layout. ## Temperature grade — commercial only The operating temperature range is 0°C to 70°C. ## Package and rework considerations The 24-SOIC wide-body package (0.295-inch body width, 7.50 mm) is a standard footprint that reworks cleanly with hot air. The T suffix means it ships in Tape & Reel — the standard for automated pick-and-place. If you need a smaller quantity for prototyping, the Cut Tape option is also available. ## Lifecycle and sourcing reality The MAX7221CWG+T is listed as Active in production — no end-of-life notice, no last-time-buy pressure. It is ROHS3 compliant. Sourcing is straightforward through independent distribution; this part is quoted to order against an RFQ with current availability and pricing confirmed at quote time.","metaTitle":"MAX7221CWG+T LED Driver, 8-Digit, 4-Wire Serial, 24-SOIC","metaDescription":"MAX7221CWG+T LED display driver IC from Analog Devices.

For a pin-compatible direct replacement, stick with the MAX7221CWG+T or its tube-shipped sibling MAX7221CWG."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX7221CWGT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX7221CWGT when reusing this data.
