Each of the six channels inverts a single input, and the Schmitt-trigger hysteresis cleans up slow or noisy edges. Supply range runs from 2 V to 6 V. Outputs source or sink 24 mA per channel. The 14-SOIC package is a common footprint for board-level glue logic. ## Supply voltage and input thresholds Rated for 2 V to 6 V supply. The low-level input threshold is 0.5 V to 1.1 V; the high-level threshold is 2.2 V to 3.9 V. ## Output drive and propagation delay Each output can source or sink 24 mA. The 10 ns propagation delay at 5 V and 50 pF load is typical for the 74AC family. Quiescent current maxes at 2 µA. ## Temperature grade and environment Rated for -40°C to 85°C, the SN74AC14DR suits industrial and commercial environments — factory-floor control cabinets, outdoor telecom enclosures, and general-purpose PCB assemblies that see temperature swings but not extreme under-hood automotive conditions. The 14-SOIC package is a standard surface-mount footprint, easy to inspect and rework. ## Lifecycle and sourcing TI lists this part as Active with ROHS3 compliance. No last-time-buy or end-of-life notice is in effect. For a BOM line that needs a hex Schmitt-trigger inverter, this is a low-risk choice for both new designs and production replenishment.","metaTitle":"SN74AC14DR 74AC Hex Schmitt-Trigger Inverter, 24 mA Output","metaDescription":"TI SN74AC14DR hex inverter with Schmitt-trigger inputs, 2 V to 6 V supply, 24 mA output drive, 14-SOIC.
