It takes one input and delivers a clean inverted output with hysteresis, rejecting slow or noisy edges on a 4.5 V to 5.5 V supply rail. 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. The -40°C to 125°C operating range covers industrial and automotive cabin environments, and the quiescent current maxes out at 1 µA, so it won't load down a lightly-regulated 5 V bus. ## 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.","metaTitle":"SN74AHCT1G14DCKR Schmitt Trigger Inverter, SC-70-5","metaDescription":"TI SN74AHCT1G14DCKR single Schmitt-trigger inverter, 4.5-5.5V supply, 8 ns prop delay at 5V/50pF, -40 to 125°C, SC-70-5.
