It takes a noisy or slow-rising input and outputs a clean, inverted logic level — the Schmitt-trigger hysteresis rejects chatter that a plain inverter would pass through. Supply range is 4.5 V to 5.5 V, making it a direct fit for 5 V TTL/CMOS systems. Propagation delay is 8 ns at 5 V with a 50 pF load, fast enough for most general-purpose logic interfaces and bus-buffering tasks. The SC-70-5 package (also known as SOT-353) saves board space — five pins, one input, one output, supply and ground. Operating temperature spans -40°C to 125°C, so it can sit on an outdoor telecom card or inside an engine-bay ECU without derating. Quiescent current is 1 µA maximum, negligible in a mixed-signal power budget. ## Schmitt-trigger input — cleans up the signal path The Schmitt-trigger input gives this inverter a low-level threshold of 0.5 V to 0.6 V and a high-level threshold of 2 V. That hysteresis window means a slowly rising sensor output or a noisy clock line won't cause multiple transitions at the output. For a field-service tech troubleshooting a glitchy digital input, swapping in this part instead of a standard inverter often clears the problem without changing the upstream sensor. ## 8 mA output drive — drives a standard logic load Output current is rated 8 mA source and 8 mA sink. That's enough to drive one or two standard TTL inputs, an LED indicator through a series resistor, or the clock input of a downstream flip-flop. It won't drive a relay coil directly — that's not what a single-gate inverter is for — but for logic-level fan-out it has margin. ## Active lifecycle — no obsolescence pressure TI lists this part as Active with RoHS3 compliance. There is no last-time-buy notice, no NRND flag, and no announced successor. For a BOM that needs a reliable 5 V Schmitt-trigger inverter, this line is stable for new designs and ongoing production.","metaTitle":"SN74AHCT1G14DCK3 TI Schmitt-Trigger Inverter, SC-70-5","metaDescription":"Texas Instruments SN74AHCT1G14DCK3 single Schmitt-trigger inverter, 4.5-5.5 V supply, 8 ns prop delay, -40 to 125 °C.
