IC 7404 Hex Inverter (NOT Gate)

The IC 7404 Hex Inverter (NOT Gate) contains six independent NOT gates that invert their input signal. It is fundamental for logic level shifting, oscillator circuits, and digital signal conditioning.

Key Features

• 6 independent NOT gates
• Standard TTL/CMOS compatible
• 14-pin DIP package
• Fast switching
• Wide availability
• Low cost
• Multiple uses per package

Technical Specifications

Applications

• Logic level inversion
• Oscillator circuits (with RC)
• Signal conditioning
• Buffer circuits
• Clock generation
• Boolean complement

Important Notes

• Unused inputs must be tied HIGH or LOW
• Two inverters can form an oscillator with RC network
• Odd number of inverters in loop creates oscillator
• HC version recommended for new designs
• Output current limited – use driver for heavy loads
