The 14-TSSOP package is a fine-pitch surface-mount (0.173\" body width, 4.40 mm), so you need a decent pair of tweezers and a steady hand for rework, but it is doable with a hot-air station. No lab bench required: if you have the footprint on the board, it swaps in the field with standard tools. ## Sourcing and lifecycle ROHS3 compliant, so it clears the current environmental directives without a waiver.","metaTitle":"SN74HCT02PW 74HCT Quad 2-Input NOR Gate, 18ns @ 5.5V","metaDescription":"TI SN74HCT02PW quad 2-input NOR gate in 14-TSSOP. 4.5V–5.5V supply, 18ns propagation delay at 5.5V, 50pF.

That is the worst-case figure across temperature and voltage; typical delays are lower."},{"question":"What is the function of SN74HCT02PW?","answer":"It is a quad 2-input NOR gate. Each of the four independent gates performs the NOR logic function: output is high only when both inputs are low. Typical use is inverting or combining digital signals in 5V logic systems."},{"question":"What is the difference between SN74HCT02PW and SN74HC02PW?","answer":"The SN74HCT02PW uses HCT logic (TTL-compatible input thresholds: 0.8V low, 2V high), while the SN74HC02PW uses HC logic (CMOS thresholds: roughly 1.5V at 5V supply). If your input signal comes from a 3.3V microcontroller, the HCT version switches more reliably on a 5V rail because its lower threshold matches TTL levels. Both are quad 2-input NOR gates in the same 14-TSSOP package."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74HCT02PW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74HCT02PW when reusing this data.
