Operating from 0.8V to 2.7V, it covers the full range of modern low-voltage core rails — 1.2V, 1.8V, and 2.5V — without a separate level translator at the input. Maximum quiescent current is 10 µA, making it suitable for battery-powered or energy-harvesting nodes where the logic idle draw must stay below the microamp range. ## Propagation delay and output drive Maximum propagation delay is 2.1 ns at 2.5V with a 30 pF load — this sets the timing closure floor for a 100+ MHz data path through a single gate. Symmetrical output drive of 9 mA source and 9 mA sink at the rated supply voltage means the gate can switch the input of five or six downstream 74AUC loads without signal degradation. The input logic levels are specified as low from 0V to 0.7V and high at 1.7V minimum — the 1V hysteresis gap provides noise margin against slow edges from RC-delayed or open-drain signals. ## Package and board integration Housed in a 5-lead SC-70-5 (SOT-353) package, the footprint occupies roughly 2.0 mm × 2.1 mm — the same land pattern as the industry-standard SOT-23-5, so it drops into existing layouts without a board spin. Surface-mount assembly with a 0.65 mm pin pitch; the small body suits dense mixed-signal boards where a single gate is needed near the load rather than routed across the board to a quad package. ## Production status and compliance Fully ROHS3 compliant, with no restricted substances above the threshold; the part carries the standard TI green marking on the reel label.","metaTitle":"SN74AUC1G02DCKR NOR Gate, 0.8V-2.7V, SC-70-5","metaDescription":"Texas Instruments SN74AUC1G02DCKR single 2-input NOR gate, 0.8V-2.7V supply, 2.1ns prop delay at 2.5V, SC-70-5.
