Learn how to construct an OR gate using diode-resistor logic in digital electronics. Explore the principles, circuit diagrams, and practical applications.

Jul 17, 2018 · An OR gate using diodes is an electronic logic gate that operates on two inputs—A and B—and outputs true if either input is true. In other words, it requires two inputs (A and B) to be either high or low in order for the output to be true.

Jul 18, 2019 · Circuit diagram of two input, positive logic OR gate using diodes and a resistor is shown below: In this logic gate circuit, \(V_a\) and \(V_b\) are inputs and \(V_{out}\) is output. These symbols can take only two values either LOW or HIGH.

Dec 26, 2013 · OR gate can be realized by Diode Resistance Logic (DRL) or by Transistor-Transistor Logic (TTL). Presently, we will learn how to implement the OR gate using DRL (Diode Resistance Logic). To realise OR gate, we will use a diode at every input of the OR gate.

Aug 12, 2019 · You can understand easily understand logic circuits made from diodes by considering ideal model of a diode in which we ignore 0.6-0.7v in-built forward voltage drop of a diode, any bulk resistance and non-idealities.

Sep 14, 2017 · Using diodes to construct an OR gate is a popular and effective approach to designing digital logic circuits. Diodes are relatively inexpensive and easy to source, which also makes them attractive to those who are just starting out in the world of digital logic circuits.

Oct 29, 2022 · Diodes can be used to create diode logic gates. Diode OR gate. The following circuit shows two 1N4148 diodes used as two input OR gate. The following is the OR gate truth table. The mathematical operation of OR gate is described by the following equation. C = A+B. The circuit symbol of an OR gate is as follows.

OR and AND logic gates made with diodes. If we need a OR gate we can use a 4071 OR CMOS IC or a TTL 7432 OR IC. If we need a AND gate we can use a 4081 AND CMOS IC or a TTL 7408 AND IC, but sometimes it is easier to use diodes. Diode Logic uses the fact that diodes conduct only in one direction.

Jul 11, 2018 · The main goal of Or Gate Diode Circuit Diagrams is to simplify complex logic operations into simpler ones. It combines logic gates (AND, OR, NOT, etc.) connected by diodes which allow for the logic to flow from one gate to the other.

Jan 17, 2022 · The below sections describe the functionality of OR gate using universal gates, diodes, and transistors. Operation of OR Gate using Diode. Below is the circuit diagram that shows OR logic gate operation using diodes.
