What is a logic gate & inverter?

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.

What are inverting NOT gates?

Inverting NOT gates are single-input components where the output is typically at a logic level "1" and switches to "LOW" or logic level "0" when the input is at logic level "1." In simple terms, it "inverts" or complements the input signal. The output will only return to "HIGH" or logic level "1" when the input goes back to logic level "0."
