It takes one input and outputs the inverted logic level, but the Schmitt trigger gives it hysteresis — the input thresholds are different for rising and falling edges. That means it cleans up noisy or slow-rising signals (think long PCB traces, mechanical switch debounce, or sensor outputs) into a clean digital waveform without extra passives. Operating temperature range is -40°C to 125°C. ## SC-70-5 footprint and board-level fit Package is SC-70-5 (SOT-353). Supplier device package is SC-70-5. The 8mA output drive (both sink and source) is enough to drive a single TTL/CMOS logic input, a low-current LED indicator, or a MOSFET gate through a series resistor. Don't expect it to drive a relay coil or a 50-ohm backplane — that's outside its rated current envelope. ## Active lifecycle — no obsolescence watch needed The SN74AHCT1G14DCKT carries an Active lifecycle status from Texas Instruments. That means no last-time-buy notice, no NRND flag, and no end-of-life risk for the foreseeable future. For a BOM line, this is a low-risk part to qualify into production — you can dual-source it across distributors without worrying about a sudden PCN. It's also ROHS3 compliant, so no conflict with EU or California RoHS requirements.","metaTitle":"SN74AHCT1G14DCKT Single Schmitt-Trigger Inverter, SC-70-5","metaDescription":"TI SN74AHCT1G14DCKT single-gate inverter with Schmitt-trigger input, 4.5V–5.5V supply, 8ns prop delay at 5V/50pF, -40°C to 125°C.
