74HC02 Quad 2 Input NOR Gate IC (7402) DIP 14 Package

74HC02 Quad 2 Input NOR Gate IC (7402) DIP 14 Package

The 74HC02 is a high-speed CMOS Quad 2-Input NOR Gate IC that integrates four independent NOR gates in a single 14-pin Dual Inline Package (DIP). Each gate performs the logic NOR operation, one of the fundamental Boolean functions widely used in digital circuits.

Built using advanced CMOS technology, the 74HC02 offers low power consumption, high noise immunity, and fast switching speeds, while maintaining compatibility with TTL logic levels. This makes it ideal for use in digital logic design, control systems, timing circuits, and microcontroller applications.

The DIP-14 package makes the IC easy to use in breadboard prototyping and PCB designs, suitable for both educational and industrial-grade electronic projects.
