Overview
The MC74AC14DR2G, produced by onsemi, is a high-performance silicon-gate CMOS hex inverter Schmitt trigger. This device contains six logic inverters that accept standard CMOS input signals and provide standard CMOS output levels. It is designed to transform slowly changing input signals into sharply defined, jitter-free output signals, offering a greater noise margin compared to conventional inverters. The MC74AC14DR2G is available in a 14-lead TSSOP package and is Pb-free, halogen-free, and RoHS compliant.
