Integrated circuits designed to implement a Boolean function. It performs a logical operation on one or more binary inputs and produces a single binary output
There are seven basic logic gates: AND, OR, XOR, NOT, NAND, NOR and XNOR. Some logic gates can have Schmitt trigger inputs. Most logic gates have two inputs and one output, but they may also be combined together to implement a circuit with more than two inputs which performs one of the logic functions.
