Logic gate circuits (Various logic families) PDF fileCircuit Diagram: DTL NAND Circuit The DTL NAND gate combines the DTL inverter with a simple Diode-Resistor Logic (DRL) AND gate as shown in its circuit diagram. Thus, any number of inputs can be added simply by adding input diodes to the circuit. The problem of signal degradation NOR Gate using Diode and Transistor (DTL) This is a very simple NOR gate circuit construction using a pair of diodes and a transistor. The implementation is on a solderless breadboard using discrete components. This diagram shows how to make a simple DTL circuit that has the same function as a NOR gate. The design is very similar to the transistor gates shown in this multi-part article. Logic Gates - Electronic Circuits and Diagrams-Electronic Discrete OR gates may be realized by using diodes or transistors. The inputs represented as X and Y may be either 0V or +5V correspondingly. The output is represented by Z . In the diode of OR gate, when both the inputs are of same value, X=0V and Y= 0V, then both the diodes are in OFF condition.
