Single Schmitt-trigger inverter for 5 V signal conditioning
The SN74AHCT1G14DBVR is a single-channel inverter from TI's 74AHCT family, with a Schmitt-trigger input that cleans up slow or noisy edges before inverting. It runs on a 4.5 V to 5.5 V supply and delivers 8 mA of output drive in both high and low states. The SOT-23-5 footprint fits tight board layouts where a single gate is all that's needed — no wasted package space. The Schmitt-trigger input gives this part a defined hysteresis window: the low-to-high threshold sits at 2 V, while the high-to-low threshold falls between 0.5 V and 0.6 V. That gap rejects noise on slowly rising or falling signals — think RC-delayed reset lines, switch debounce, or sensor outputs with long rise times. A standard inverter would oscillate or produce multiple edges on the same transition; this one holds a clean output. Temperature range spans -40°C to 125°C, so it's at home in industrial cabinets, outdoor telecom gear, or under-hood automotive modules that see thermal cycling. Quiescent current maxes out at 1 µA, keeping the standby draw negligible in battery-backed or always-on circuits.
Propagation delay is 8 ns typical at 5 V with a 50 pF load.
No last-time-buy notices or obsolescence warnings are documented.
If you're qualifying it for a production BOM, the active lifecycle and wide temperature grade remove the usual supply-chain red flags.
