Flip flops are simple logic circuits used to store binary information. The DM74ALS273WM is a type of flip flop known as a positive edge-triggered D-type Flip-Flop. It is one of many types of devices used in computer and electronic circuits for its ability to reliably store binary data.

The DM74ALS273WM is a dual in-line package (DIP) device with 20 pins. It includes two trigger inputs and two outputs, one which is normally state of 1 and the other typically in a 0 state. As the name suggests, it can be triggered by either a positive or negative pulse on its input. A positive pulse causes the state of the output to be determined by the data input, while a negative pulse (or reset) will cause the output to reset to its initial state.

A simple block diagram for the DM74ALS273WM is shown below. The Data inputs (D) determine the state of the outputs (Q1 and Q2), and the CLK (clock) input determines when the input is sampled and the data is loaded into the flip-flop. The CLR (clear) input is used to reset the output to the initial state.

The DM74ALS273WM is widely used in digital electronics circuits, especially in devices that require the reliable storage and retrieval of data. Its main application is as a storage element, where it can hold a single bit of data as long as power is supplied to the circuit. It is also often used as a logic element to control the flow of data within a digital circuit.

The DM74ALS273WM is relatively easy to use and very reliable in operation. It has been used in many popular electronic products, from desktop computers and smartphones to TVs and even self-driving cars. Its durability and reliability have made it a popular choice for many applications.

The working principle of the DM74ALS273WM involves the transfer of a data bit (0/1) from the Data inputs to the outputs (Q1 and Q2) only when the CLK input is triggered. It is a positive edge-triggered device, which means that the CLK input must have a positive edge (rising from low to high voltage levels) in order to trigger the transfer of the data. Once triggered, the Data input at that time will be stored into the flip-flop and propagated to the outputs.

The CLR input is used to reset the output to its initial state. It is typically connected to ground, but can be connected to a voltage source to reset the state of the outputs. This is useful for resetting the circuit after a power failure or any other type of reset required.

Overall, the DM74ALS273WM has been a dependable and reliable device used in many different types of digital circuits over the years. It is a powerful and simple logic element that can be used to store and transfer data quickly and reliably. It may be small, but it has had a major impact on the evolution of digital electronics.
