The SN74LVCU04APWR: The laser-etch on the 14-TSSOP body should match TI's standard date-code format for the 74LVCU family — any deviation in font or pad geometry warrants a decap check.
3.8 ns propagation delay — what it buys you
At 3.3 V with a 50 pF load, the part delivers a maximum propagation delay of 3.8 ns. The 24 mA symmetric output drive keeps the edge rate fast.
Supply range and input thresholds
Input low thresholds sit at 0.4 V to 0.65 V; input high thresholds run 1.32 V to 2.88 V — these track the supply, making the inverter compatible with both LVCMOS and lower-voltage logic families. Quiescent current is a maximum 10 µA, negligible for battery-powered equipment.
The 0.65 mm pin pitch matches standard fine-pitch soldering profiles. No exposed thermal pad — dissipation is handled through the leads, so keep the ambient below 85°C if you are running all six gates at full 24 mA output simultaneously.
