Products in the logic gate and inverter family perform elementary logical operations on individual logic signals such as AND, NOT, OR, etc. Unlike flip-flops they do not have a capacity to store information and respond immediately to the signals presented to their inputs. Though long supplanted by implementations in integrated circuit form for realizing complex functions, discrete gates remain available for use in circumstances where only very simple logical functions are needed.
