The 7.5 ns propagation delay at 5 V with a 50 pF load sets the timing floor for a 5 V logic path — fast enough for most glue-logic and bus-interface roles without the shoot-through current of a faster AC family. ## Supply rail and logic thresholds The input low threshold is 0.8 V and the high threshold is 2 V, which means it interprets a standard 5 V CMOS or TTL output correctly but may not see a 3.3 V signal as a valid high without a level shifter. Quiescent current maxes at 1 µA, so it adds negligible draw to a 5 V rail. ## Active production, SOT-23-5 footprint The SOT-23-5 (SC-74A) footprint is a standard small-outline transistor package — the same land pattern as many single-gate logic parts, so it drops into existing layouts without a pad revision.","metaTitle":"SN74AHCT1G02DBVR NOR Gate – Texas Instruments 74AHCT","metaDescription":"Single 2-input NOR gate, 4.5V–5.5V supply, 8 mA output drive, 7.5 ns prop delay at 5V/50pF.
