74LS08 quad 2 input AND gate Dip IC

74LS08 quad 2 input AND gate Dip IC

The 74LS08 is a Quad 2-Input AND Gate IC, meaning it contains four independent AND gates, each with two inputs and one output.

It belongs to the 74LS (Low Power Schottky TTL) logic family, which provides fast switching speed, low power consumption, and TTL-compatible voltage levels.

Each gate performs the logical AND operation, where the output is HIGH only when both inputs are HIGH.
This IC is commonly used in digital logic circuits, timing, control systems, and arithmetic operations.

Features

• Contains 4 independent 2-input AND gates
• TTL compatible logic levels
• Fast switching (typical propagation delay ~10 ns)
• Low power dissipation due to Schottky clamping
• Wide operating voltage range: 4.75V – 5.25V (typically 5V)
• Standard 14-pin Dual Inline Package (DIP-14)
• Input and output buffering for reliable operation
• Operating temperature range: 0°C to +70°C

Functional Description

Each gate in the 74LS08 takes two binary inputs and produces one binary output:

• If both inputs are HIGH (1) ? Output = HIGH (1)
• Otherwise ? Output = LOW (0)

All four gates are independent, meaning they can be used separately in different parts of a circuit.

Applications

• Basic digital logic operations
• Arithmetic logic circuits (e.g., adders, comparators)
• Control logic and signal gating
• Data routing and selection circuits
• Timing pulse generation
• Multiplexer logic
• Digital communication and embedded systems
