Supply and temperature — board-level fit
Supply voltage range is 4.5 V to 5.5 V. Operating temperature range is -40°C to 85°C. Quiescent current is 2 µA maximum.
Schmitt-trigger hysteresis — why it matters for signal conditioning
Low-level input thresholds are 0.5 V to 0.6 V; high-level thresholds are 1.9 V to 2.1 V. Output current is 8 mA source and sink.
Lifecycle and sourcing
TI lists the SN74AHCT14DR as Active and ROHS3 compliant. No end-of-life notice or last-time-buy window is in effect, so it remains a standard catalog item for new designs and production replenishment.
