7404 Hex Inverter NOT Gate IC (DIP)

7404 Hex Inverter NOT Gate IC (DIP) Overview

The 7404 Hex Inverter NOT Gate IC is a classic TTL logic device that contains six independent inverters. Each inverter outputs the opposite logic level of its input, making the 7404 a fundamental building block for digital logic, signal conditioning, and timing circuits. Packaged in a standard 14-pin DIP, the 7404 is well suited for breadboard prototyping, classroom experiments, and professional designs.

Key Features

• Six independent NOT gates (hex inverter) in one chip
• TTL 74xx logic family, standard-performance device
• Operating voltage: 4.75 V to 5.25 V (typical 5 V)
• Standard 14-pin DIP package for easy prototyping and mounting
• High-speed switching suitable for signal inversion and waveform shaping
• Breadboard and PCB friendly design

Specifications

• Device: 7404 Hex Inverter (NOT gates)
• Logic family: TTL (74xx)
• Number of gates: 6 independent inverters
• Package: 14-pin DIP (Dual Inline Package)
• Operating voltage: 4.75 V to 5.25 V (use stable 5 V supply for best results)
• Typical use: signal inversion, logic manipulation, waveform generation

Common Applications

• Logic signal inversion and level shaping
• Waveform shaping and timing circuits
• Oscillator and clock generation circuits
• Digital circuit prototyping and experimentation
• Educational labs, training kits, and DIY electronics projects

Typical Usage Tips

• Always use a 0.1 µF decoupling capacitor close to VCC and GND to reduce supply noise.
• Avoid leaving inputs floating. Tie unused inputs to a defined logic level through resistors or directly to VCC or GND as appropriate.
• Observe proper supply polarity and ensure VCC is within the specified range to prevent damage.
• For breadboard use, confirm correct orientation of the 14-pin DIP and double-check pin connections.

Why Choose the 7404

The 7404 Hex Inverter is a reliable, inexpensive, and easy-to-use TTL logic IC. Its combination of six inverters in a single DIP package, standard TTL compatibility, and straightforward operation make it an excellent choice for students learning digital logic, hobbyists building prototypes, and engineers developing larger systems.
