In digital electronics, a NAND gate (NOT-AND) is a logic gate which produces an output which is false only if all its inputs are true; thus its output is complement to that of an AND gate. A LOW (0) output results only if all the inputs to the gate are HIGH (1); …

反及閘 （英語： NAND gate）是數位邏輯中實現 邏輯與非 的 邏輯閘。 若輸入均為高電平（1），則輸出為低電平（0）；若輸入中至少有一個為低電平（0），則輸出為高電平（1）。 反及閘是一種通用的邏輯閘，因為任何 布林函數 都能用反及閘實現。 使用特定邏輯電路的數位系統利用了反及閘的函數完備性（功能完備性）。 複雜的邏輯表達式常以其他邏輯函數表示，如 與 、 或 、 非，而將表達式改寫為用邏輯與非表示的式子可以節約成本，因為使用反及閘實現電路 …

The CD4011 is a CMOS chip with four NAND gates. Because each gate has two inputs and it has 4 gates inside, it’s usually called a Quad 2-Input NAND Gate. A NAND gate combines the functionality of AND and NOT gates. It gives a LOW output only when all inputs are HIGH; otherwise, the output is HIGH.

As the only configuration of the two inputs that results in a low output is when both are high, this circuit implements a NAND (NOT AND) logic gate. A NAND gate is a universal gate, meaning that any other gate can be represented as a combination of NAND gates. A NOT gate is made by joining the inputs of a NAND gate together.

逻辑门是用于实现布尔表达式（特别是二值布尔表达式）的基本电子电路。 它们提供了一种基于 布尔代数 定律组合和处理数字信号的方法。 在数学上，我们可以使用布尔代数来处理二进制数并简化逻辑表达式。 但在数字系统中实际实现时，我们使用称为逻辑门的简单电子电路。 以下是一些用于构建数字逻辑电路的基本逻辑门。 让我们详细了解这些逻辑门，看看它们的逻辑符号，并建立它们的真值表。 NOT 逻辑门具有一个输入和一个输出，其中输出是输入的补码。 如果输入 …

2020年7月25日 · NAND和NOR门被称为通用逻辑门 ，因为我们只能单手使用 NAND或NOR门 来实现任何逻辑电路或门。 Although the logic circuit of any complexity can be realized using three basic gates i.e., AND, OR, NOT Gates, but they can also be realized using only a single type of gate, that is why sometimes NAND and NOR gates are called "universal building blocks".

Digital Electronics Tutorial about the Logic NAND Gate and the Logic NAND Gate Truth Table used in digital TTL and CMOS logic gate circuits

2024年11月27日 · NAND Gate is the special type of logic gate which is also known as the Universal Gate, because it can be used to implement other basic logic gates like AND, OR, and NOT. It performs NAND(NOT AND) operation between two or more binary inputs and gives output binary signal. This is a combination of AND gate and NOT gate.
