At 5V with a 50 pF load, the SN74LV14AD delivers a maximum propagation delay of 10.6 ns. The 74LV family sits between the original 74HC (slower, higher current) and the 74AHC (faster, lower power). If your bus needs sub-7 ns delay, the 74LVU04 variant (SN74LVU04APWT) offers 7 ns at 5V/50pF but lacks Schmitt-trigger inputs — you trade noise immunity for speed.
No last-time-buy notices are in the public record. The part is ROHS3 compliant.
Yes, the SN74LV14AD is pin-compatible with the 74HC14 and operates over the same 2V to 5.5V range. The 74LV family draws lower quiescent current (20 µA max) than 74HC, making it a better fit for battery-powered or power-sensitive designs.
