Components Needed for building XOR gate So with just the few components, we can construct a XOR gate circuit. 2N2222 (NPN) transistors x5 10kΩ resistors x3 220Ω resistors x3 Push buttons x2 Breadboard ...

It uses standard symbols for logic gates, wires, switches, power sources and other elements. A circuit diagram can help you visualize, analyze and design a circuit.

The NOR gate outputs LOW if any input is HIGH. The output is HIGH only if all inputs are LOW. Circuit Diagram: Operation: The two transistors are connected in parallel, sharing a common collector ...
