Overview
The MC74HC14ADR2, produced by onsemi, is a high-performance silicon-gate CMOS hex Schmitt-trigger inverter. This component is part of the standard logic family and is designed to handle noisy environments effectively due to its hysteresis voltage characteristics. It is available in a 14-pin SOIC package and is RoHS compliant, making it suitable for a wide range of applications. The device is useful for “squaring up” slow input rise and fall times, enhancing signal integrity in various electronic systems.
