The OR gate is a digital logic gate that implements logical disjunction. The OR gate outputs "true" if any of its inputs is "true"; otherwise it outputs "false". The input and output states are normally represented by different voltage levels. Any OR gate can be constructed with two or more inputs.

或閘（英語： OR gate ）是數位邏輯中實現邏輯或的邏輯閘，功能見右側真值表。只要兩個輸入中至少有一個為高電平（1），則輸出為高電平（1）；若兩個輸入均為低電平（0），輸出才為低電平（0）。

或门（OR gate），又称或电路、逻辑和电路。 如果几个条件中，只要有一个条件得到满足，某事件就会发生，这种关系叫做“或”逻辑关系。 具有“或”逻辑关系的电路叫做或门。

2012年2月24日 · 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. Just like an AND gate, an OR gate may have any number of input probes but only one output probe.

2024年11月29日 · OR GATE is most widely used digital logic circuit and is known as a primitive digital electronics building block in digital logic. The output state of OR gate will be high i.e., (1) if any of the input state is high or 1, else output state will be low i.e., 0.

Logical OR gate can have 2 or more than 2 input lines but it has one output line. It can be either true or false, true being High state”1” and false being Low state”0”. OR Gate works on submission bases. i.e. If either “A” or “B” is “1”, Then “C” is 1. Good to know: These terms also used in binary logic gates and circuits. 0 or 1. Low or High.

2015年11月6日 · The OR gate performs logic addition, more commonly known as the OR function. An OR gate has two or more input signals with only one output signal. In OR gate, output voltage is high if any or all of the input voltages are high. Diodes may be used to build an OR gate, as shown in the Fig 1 . Fig 1.

The Logic OR Gate is a type of digital logic circuit whose output goes HIGH to a logic level 1 only when one or more of its inputs are HIGH. The output, Q of a “Logic OR Gate” only returns “LOW” again when ALL of its inputs are at a logic level “0”. In other words for a logic OR gate, any “HIGH” input will give a “HIGH”, logic level “1” output.

2022年1月17日 · This article has provided a detailed explanation of how an OR gate performs, its circuit diagram, truth table, gate ICs, examples, and applications. Also, know what is wired-OR gate using open-collector NOR gates?

In digital electronics, the OR gate is a type of basic logic gate that produces a high or logic 1 output when at least one of its inputs is high or logic 1. It produces a low output or logic 0 when all of its inputs are low or logic 0. The logic symbols of two-input and three-input OR gates are depicted in the following figure.
