In electronics circuits, digital logic or boolean logic represents signals and sequences in a digital circuit. These rules allow us to make complicated decisions based on simple binary (yes/no) questions, ultimately forming the basis for how circuits and hardware communicate.
Logic components perform different functions on inputs. These include gates, multiplexers, encoders, decoders, flip-flops, and comparators. The most common type of logic component is a logic gate,which also comes in several variations: AND, OR, NOT, NAND, NOR, XOR, and XNOR.
Logic gates are typically used in integrated circuits (ICs). At any given moment, they are in one of two binary conditions, represented by the numbers 0 and 1. Depending on the type of gate and the combination of inputs, the output will differ.
When designing in logic devices, it's important to consider voltage level compatibility, the number of inputs a gate can drive, and the number of gates that can be driven by the output of a gate, as well as timing constraints.
