Logic circuits, such as flip flops, are used in a wide range of applications. The MC74AC74DG is an integrated circuit that is often employed in these applications. This article will overview the working principle and main application fields for the MC74AC74DG.

The MC74AC74DG is a Dual D-Type Flip-Flop integrated circuit. A Flip-Flop, sometimes called a bi-stable, is a circuit whose output can assume one of two stable, but opposite values or states in response to a small change in the input signal. The MC74AC74DG has two positive and two negative trigger inputs, which are denoted T\textsubscript{p}1, T\textsubscript{n}1, T\textsubscript{p}2, and T\textsubscript{n}2. The Flip-Flop works in the following way: first, the T\textsubscript{p}1 and T\textsubscript{n}1 input triggers must both be true for the circuit to begin an evaluation. Once both triggers are true, the circuit then looks to the T\textsubscript{p}2 and T\textsubscript{n}2 inputs to determine the values of the Q and Q’ outputs. If T\textsubscript{n}2 is true, the Q output will be set to one and the Q’ output to zero. If T\textsubscript{p}2 is true, the Q output will be set to zero and the Q’ output to one.

The MC74AC74DG is often applied in various digital electronics applications. In digital electronics, the Flip-Flop is often used to form the fundamental building blocks of digital devices and systems, such as memory registers, counters, shift registers and various other types of digital devices.
