Active production — no end-of-life risk for this BOM line
The SN74LVC2G04DCKR is an active-production dual inverter from Texas Instruments' 74LVC series, so there is no imminent obsolescence concern for designs using this part.
Propagation delay and output drive — what they mean for signal integrity
Maximum propagation delay is 3.2ns at 5V with a 50pF load — this sets the upper bound on data rate through the inverter; for a 50% duty-cycle signal the theoretical toggle rate is about 156 MHz, but real margin depends on the output rise time into the actual load capacitance. Quiescent current is 10 µA maximum, so the part adds negligible overhead in battery-powered or always-on sections of the board.
