Oct 30, 2019 · OR Gate using Transistor – Circuit Diagram . The first version of the OR gate is the simplest one – it consists of two paralleled emitter followers sharing a common emitter resistor. The above circuit diagram shows the simplest way to build an OR gate using NPN transistors.

Sep 6, 2022 · In this post I have explained how to build NOT, AND, NAND, OR, and NOR logic gates using discrete transistors. The main advantage of using transistor logic gates is that they can work even with voltages as low as 1.5 V.

Nov 29, 2024 · OR Gate Circuit Diagram Using Transistors. An OR gate can be made using transistors, typically with NPN transistors in a basic configuration. The basic idea of this combination is to control the output using two inputs, where either input can turn on a transistor, resulting in a high output (1).

Build a OR Gate From Transistors: In this guide I will show you how to build an OR gate with two transistors. For a basic detail of how the NPN transistor is being used in this project, please see the intro message to my AND gate instructable.

Oct 2, 2019 · By strategically connecting transistors together, an Or Gate Circuit can be used to route electrical signals throughout a device, adding functionality and expanding the capabilities of a circuit. At its core, an Or Gate Circuit consists of two input transistors and an output transistor.

Jul 2, 2024 · OR Gate 2 Circuit Diagram. The circuit diagram for AND gate 2 is shown above. This shows the connections of each individual component. The circuit requires three transistors, four 2K resistors, connecting wires, and an LED. Resistor values from 330 ohms to 2K will work. The direction of the LED is going out of the circuit.

In this article, we go over how to build an OR gate circuit with transistors. Transistors are the building blocks of logic gates, such as NOT gates, OR gates, AND gates, and NAND gates, and gates are the building blocks of integrated circuits.

Jul 18, 2019 · In this post, we will see how basic digital gates can be made with the help of diodes and transistor. OR gate has two or more inputs and only one output. The output of the OR gate is HIGH if one or more inputs are HIGH. Circuit diagram of two input, positive logic OR gate using diodes and a resistor is shown below:

Nov 8, 2016 · Fig. 2: Circuit Diagram of Transistor based OR Gate. How It Works. The transistors are connected in parallel and their bases are used as input. The base of both the transistors act like input and one of the emitters of both the transistors is used to derive the output.

Feb 24, 2012 · Transistor Circuit: Transistors can also form an OR gate, providing a high output if any transistor is switched on. What is an OR Gate? An OR gate is a logic gate that performs logical OR operation. A logical OR operation has a high output (1) if one or both the inputs to the gate are high (1). If neither input is high, a low output (0) results.
