An OR gate is a building block of digital logic circuits. It takes multiple binary inputs and produces a single output based on the logic of the OR operation. The OR operation is akin to logical addition, where the output is “1” if any of the inputs are “1”, and “0” only if all the inputs are “0”.
In a NOR gate, the output is 1 (True) only when both inputs are 0 (False). For all other input combinations, the output is 0 (False). This behavior can be summarized as “If neither A nor B is True, then the output is True.”
The CD4011 NAND gate is one of the most commonly used gates in digital electronics because of its simplicity and versatility.
