2.8 ns propagation delay — timing budget for the 3.3 V bus
The SN74ALVC04DE4 is a hex inverter from TI's 74ALVC family, packing six independent inverter gates in a 14-SOIC package. Its headline number is the 2.8 ns max propagation delay at 3.3 V with a 50 pF load — that's the figure that decides whether this part holds timing in a high-frequency clock distribution or a fast data path. The 1.65 V to 3.6 V supply range makes it a natural fit for mixed-voltage boards where a single inverter needs to sit on a 1.8 V or 2.5 V rail alongside 3.3 V logic. Each of the six channels can source or sink 24 mA, enough to drive a handful of CMOS loads or a short unterminated trace directly. Quiescent current maxes out at 10 µA, so the part won't be a factor in standby power budgets.
Industrial temperature grade — not just a desk part
The input logic thresholds scale with supply: low-level at 0.7 V to 0.8 V, high-level at 1.7 V to 2 V, so the switch point tracks the rail rather than being fixed to a 5 V legacy level.
