The Toshiba 7UL1G02FU,LF is a single 2-input NOR gate from the 7UL series, aimed at board-level glue logic where propagation delay and supply flexibility matter more than raw drive. The headline number is 4.4 ns max at 3.3 V with a 30 pF load, which keeps signal-integrity margin tight in a 50–100 MHz clock domain. If you are stitching together asynchronous resets or gating a slow peripheral, this part fits without adding a dead cycle.
The supply window runs from 0.9 V up to 3.6 V, so the same part works in a 1.8 V MCU domain and a 3.3 V peripheral bus. Quiescent current maxes out at 1 µA, which matters if the gate stays powered in a sleep mode.
The 5-pin SSOP package — also listed as 5-TSSOP, SC-70-5, SOT-353 — is a common small-outline footprint for single-gate logic. Surface-mount only.
