IC 7432 Quad 2-Input OR Gate

The IC 7432 Quad 2-Input OR Gate contains four independent OR gates. Each gate outputs HIGH when any input is HIGH, making it essential for combinational logic, decision-making circuits, and alarm systems.

Key Features

• 4 independent 2-input OR gates
• Standard TTL/CMOS compatible
• 14-pin DIP package
• Fast propagation delay
• Wide availability
• Low cost
• Multiple uses per package

Technical Specifications

Applications

• Combinational logic
• Alarm systems
• Signal combining
• Decision circuits
• Digital control
• Boolean OR implementation

Important Notes

• Unused inputs must be tied LOW (not left floating)
• Can combine with AND gates for complex logic
• 74HC32 recommended for modern designs
• Decouple power supply
• Output current limited for direct load driving
