Product details

Single-gate Schmitt inverter for noisy 5 V rails

The Texas Instruments SN74AHCT1G14DCKR is a single Schmitt-trigger inverter from the 74AHCT series, in a 5-pin SC-70-5 package. Propagation delay sits at 8 ns typical with a 50 pF load at 5 V — fast enough for most board-level glue logic and signal conditioning tasks.

Schmitt trigger — what it buys you on a real board

The Schmitt-trigger input cleans up a slow-rising sensor output, a long PCB trace, or a pushbutton debounce line. Low-level threshold is 0.5 V to 0.6 V; high-level is 2 V.

Frequently asked questions

Is SN74AHCT1G14DCKR RoHS compliant?

Yes, it carries ROHS3 compliance status.

What is the closest functional equivalent to SN74AHCT1G14DCKR?

The SN74AHC1G00DBVT is a 2-input NAND gate in the same SC-70-5 footprint and 5 V supply range, but with a different logic function and no Schmitt trigger. For a direct Schmitt-trigger inverter replacement, stay within the 74AHCT1G14 family — the SC-70-5 variant is the same die in a smaller package than the SOT-23 option.
