74LVC2G14 — Datasheet Summary, Specs & Alternatives

01 — Overview

This datasheet covers the 74LVC2G14, a dual inverting Schmitt trigger logic device available in five package variants. It serves as a technical reference for designers needing high noise immunity and mixed-voltage translation between 3.3 V and 5 V systems. Key parameters include a wide supply range of 1.65 to 5.5 V, ±24 mA output drive at 3.0 V, and overvoltage tolerant inputs up to 5.5 V. The chip features low power dissipation, unlimited rise/fall times, and built-in I circuitry for safe partial power-down operation.
