Overview
7404 / SN74LS04N Hex Inverter IC
The 7404 / SN74LS04N Hex Inverter IC is a versatile digital logic component featuring six independent NOT gates in a single 14-pin package. Each inverter accepts one digital input and produces the opposite logic state at its output.
A HIGH input produces a LOW output, while a LOW input produces a HIGH output, making the 7404 useful whenever a complementary or inverted digital signal is required.
Its DIP-14 through-hole package is well suited for breadboard prototyping, educational electronics, circuit development, and PCB assembly. The six independent inverter channels allow multiple signals to be inverted using a single IC.
The 7404 is a practical component for digital logic circuits, signal inversion, control systems, oscillator circuits, Arduino interfaces, and electronics learning projects.

Product Technical Information
Technical Details
7404 / SN74LS04N Hex Inverter
The 7404 is a classic digital logic IC containing six independent NOT gates, also known as inverters. The SN74LS04N is a specific member of the 74LS04 family designed using Low-Power Schottky TTL technology.
Each inverter has one input and one output. The output is always the logical opposite of the input.
NOT Gate Operation
The basic operation is straightforward:
| Input | Output |
|---|---|
| LOW | HIGH |
| HIGH | LOW |
This makes the IC useful for generating complementary digital signals and reversing logic states.
Six Independent Inverters
Six separate inverter gates are integrated into a single DIP-14 IC. This allows several digital signals to be inverted without requiring multiple individual ICs.
The available gates can be used independently or combined to create more complex digital circuits.
DIP-14 Through-Hole Package
The 14-pin DIP package is ideal for:
- Breadboard prototyping
- Educational electronics
- Digital logic experiments
- Through-hole PCB assembly
- DIY electronics projects
Digital Circuit Applications
The 7404 can be used for:
- Logic signal inversion
- Complementary signal generation
- Digital switching
- Logic-level interfacing
- Oscillator circuits
- Pulse shaping
- Timing circuits
- Control systems
- Arduino projects
- Digital electronics education
SN74LS04N
The SN74LS04N belongs to the 74LS TTL logic family. Its electrical characteristics, including supply voltage, input thresholds, output current, and propagation delay, should be considered when integrating it with other logic families or microcontrollers.
Note: Always verify the exact manufacturer datasheet for the supplied IC before designing a circuit, particularly for pin configuration and electrical specifications.
