It integrates four independent NOR gates, each with two inputs, and operates across a supply range of 2V to 5.5V. This part is suited for general-purpose logic gating in industrial control, motor drives, and automotive electronics where the -40°C to 125°C temperature range covers under-hood and factory-floor environments. ## Speed and timing margin Maximum propagation delay is 8.5ns at 5V with a 50pF load. That places the SN74AHC02N in the fast-logic tier — fast enough for most microcontroller bus decoding and clock gating below 50 MHz, but not a candidate for RF or high-speed serial links. The 2 µA quiescent current keeps the power budget negligible in always-on or battery-backed sections of the board. ## Lifecycle and sourcing reality The SN74AHC02N carries an active lifecycle status and is ROHS3 compliant. For BOM lines that require a through-hole NOR gate, this part is a straightforward, long-availability choice.","metaTitle":"SN74AHC02N TI 74AHC Quad 2-Input NOR Gate, 14-DIP","metaDescription":"SN74AHC02N from TI: 74AHC series quad 2-input NOR gate in 14-DIP. 2V to 5.5V supply, 8mA output drive, -40°C to 125°C.

The AHC family offers faster propagation delay — 8.5ns versus 19ns for the HC equivalent at 5V — and maintains the same 2V to 5.5V supply range. Pinout and function are identical, so the AHC part is a direct speed upgrade for existing HC sockets."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74AHC02N","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74AHC02N when reusing this data.
