You need a NOR gate with three inputs and you don't want to wire two 2-input gates in series just to get there. The 4025 gives you three independent 3-input NOR gates on one chip. CMOS, low draw, straightforward. Your logic simplifies, your breadboard gets less crowded, and the project moves forward. That's the whole point
