The 125°C ceiling is the junction temperature — derate the 8 mA output if ambient plus self-heating pushes toward that limit in a still-air enclosure. ## Timing — 8.5 ns at 5V Max propagation delay is 8.5 ns with a 5V supply driving 50 pF. ## Quiescent draw and always-on circuits Quiescent current maxes at 2 µA across the full voltage range. That makes this gate a candidate for battery-backed power-management logic or always-on supervisory circuits where every microamp counts. ## Lifecycle and sourcing posture TI lists this part as Active and ROHS3 compliant.","metaTitle":"SN74AHC02RGYR Quad 2-Input NOR Gate, 74AHC, 2V-5.5V","metaDescription":"TI SN74AHC02RGYR quad 2-input NOR gate, 74AHC series, 2V to 5.5V supply, 8.5ns prop delay at 5V, -40°C to 125°C, 14-VFQFN.

If your driving device is a 5V TTL output, the AHCT version gives cleaner noise margin. For pure CMOS or 3.3V logic, the AHC version is the standard choice."},{"question":"Does SN74AHC02RGYR have a cross-reference to other NOR gates?","answer":"No single-gate NOR direct cross is listed. The closest functional sibling in the 74AHC family is the single-gate NAND SN74AHC1G00DBVT or the single-gate OR SN74AHC1G32DCKT, but those are different logic functions. For a quad NOR replacement, look at the 74AHC02 in alternate packages (SOIC, TSSOP) rather than a different logic type."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74AHC02RGYR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74AHC02RGYR when reusing this data.
