7402 Quad 2-Input NOR Gate Logic IC – DIP-14

The 7402 is a digital logic integrated circuit that contains four independent 2-input NOR gates in a single package. As part of the classic TTL (Transistor-Transistor Logic) family, it operates from a single 5V supply and delivers reliable switching performance for digital systems. The 7402 IC is widely used in combinational logic, control systems, timing circuits, and educational electronics projects. With its standard DIP-14 package, it is ideal for breadboard prototyping and PCB-based digital designs.
