Product details

Supply and temperature — board-level fit

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.

Frequently asked questions

Is SN74AHCT14DR RoHS compliant?

Yes, it is ROHS3 compliant per TI's listing.

What are alternatives to SN74AHCT14DR?

The SN74HCS04PWR (74HCS series) offers Schmitt-trigger inputs with a wider 2 V to 6 V supply and -40°C to 125°C range, but its propagation delay is 16 ns at 6 V/50 pF — slower than the 8 ns of the SN74AHCT14DR at 5 V. The SN74LVU04APWT (74LVU series) runs at 2 V and has a 7 ns delay at 5 V/50 pF, but lacks Schmitt-trigger hysteresis. For a direct functional drop-in with the same pinout, verify the supply and timing requirements against your design.
