74HC04 / 7404 Hex Inverter (NOT Gate) IC – High-Speed CMOS Logic DIP-14 for Arduino & Robotics

Overview 

The 74HC04 is a 14-pin Integrated Circuit featuring six independent Inverters (NOT gates). Unlike older TTL chips, the “HC” (High-speed CMOS) version is designed for modern circuits, offering a wide operating voltage and very low power consumption. It is commonly used to “clean up” noisy digital signals, provide delay lines, or simply reverse the logic of a sensor output so it works with your specific code.

Key Features

• Six Independent Gates: 6 individual NOT gates in a single DIP-14 package.

• Logic Inversion: Standard NOT gate operation—converts HIGH to LOW and LOW to HIGH.

• Wide Supply Range: Works from 2.0V to 6.0V, making it a perfect match for 3.3V and 5V microcontrollers.

• Low Input Current: CMOS technology ensures it won’t “load down” your signal source.

• Breadboard Ready: Standard through-hole DIP package for easy prototyping and student projects.
