This document introduces the features and characteristics of the SN54AC14/SN74AC14 series products, including the operating voltage range, the input voltage range, the maximum propagation delay, etc.
The SN54AC14 (also marked as SN74AC14) is a hex Schmitt‑trigger inverter that provides six independent inverting stages. The device features separate positive‑going and negative‑going input thresholds, giving it a wide noise margin and jitter‑free output even with slow input ramps.
The part is offered in a variety of packages (PDIP, SOIC, SSOP, TSSOP, etc.) with detailed ordering information and thermal data available on the TI website. An important notice about availability, warranty and usage in critical applications appears at the end of the data sheet.
