Typical applications include combinatorial logic gating, address decoding, and glitch-free enable/disable circuits where the NOR function simplifies the logic tree. The through-hole DIP package is prototyping-friendly and remains common in Mil/Aero repair and legacy control boards. ## Supply range and temperature grade — what they mean for the BOM The -55°C to 125°C operating temperature range is the full Mil-spec span. ## Lifecycle and sourcing The CD74HC4002E is listed as Active with ROHS3 compliance. It is a current-production part from Texas Instruments' 74HC line, available through independent distribution. For BOM planning, this part carries no near-term obsolescence risk.","metaTitle":"CD74HC4002E NOR Gate, 74HC, 2V-6V, -55°C to 125°C, 14-DIP","metaDescription":"CD74HC4002E dual 4-input NOR gate, 74HC series, 2V to 6V supply, 2 µA quiescent, 17ns @ 6V, 50pF.

The key difference is logic function: the CD74HC4002E is a NOR gate, while the SN74HC21N is an AND gate. The SN74HC21N has a narrower commercial temperature range (-40°C to 85°C) versus the CD74HC4002E's -55°C to 125°C. For a pin-compatible NOR-to-AND substitution, the board logic must accommodate the inverted output."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CD74HC4002E","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CD74HC4002E when reusing this data.
