For a 10 MHz clock buffer, the 11.5 ns leaves under 88 ns of the period for the rest of the path, so verify the cumulative delay against your setup/hold requirements. Quiescent current maxes at 2 µA, so the part adds negligible static draw to a 5 V rail — useful in always-on sense circuits where every microamp counts. Input logic thresholds are asymmetric: low is 0.5 V to 1.4 V, high is 1.2 V to 2.1 V. That hysteresis window (~0.7 V typical) is what rejects the noise on a slowly rising sensor output or a long backplane trace. ## Production status and package availability The 14-SOIC (3.90 mm body width) is a common footprint shared with many 74-series logic devices, so board spins are straightforward.

The ACT variant typically offers faster propagation delay at 5 V and higher output drive (24 mA vs 5.2 mA for HC14), but the HC14 operates down to 2 V. If your board is strictly 5 V and you need the extra drive, the ACT14 is the better fit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74ACT14D","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74ACT14D when reusing this data.
