The SN74HC08N (7408) is a digital logic IC that contains four independent 2-input AND gates in a single chip. It is widely used in electronics projects to perform basic logical operations.
⚡ Key Features
- Quad AND Gates:
Contains 4 separate AND gates (each with 2 inputs and 1 output) - High-Speed CMOS Technology:
Faster and more power-efficient than older TTL versions - Wide Voltage Range:
Operates from 2V to 6V - Low Power Consumption:
Ideal for battery-powered and low-power circuits - DIP-14 Package:
Easy to use with breadboards and DIY projects
🔌 How It Works
👉 Each AND gate gives output based on inputs:
| Input A | Input B | Output |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 1 |
✔ Output is HIGH (1) only when both inputs are HIGH
📌 Pin Configuration (DIP-14)
- 4 AND gates inside the IC
- Each gate has:
- 2 Inputs (A, B)
- 1 Output (Y)
- Includes VCC (power) and GND
🧰 Applications
- Digital circuits & logic design
- Arduino & microcontroller interfacing
- Signal control systems
- Educational electronics projects
⚠️ Important Notes
- Do not exceed 6V supply voltage
- Use proper grounding to avoid noise
- Compatible with most digital logic systems
💡 Simple Explanation
👉 It’s a logic chip that says “YES” only when both inputs are YES —
otherwise, the output stays OFF.
