SN74ACT1284PW Application Field and Working Principle

The SN74ACT1284PW is a specialized integrated circuit (IC) that can be used to provide a 16-bit parallel synchronous data storage for a variety of applications. It is a generic component that finds itself deployed in a wide array of devices, from consumer electronics such as games consoles and DVD players to industrial-grade hardware such as robotics, aerospace components, and factory automation equipment. This heavy-duty component is designed for reliability and accuracy, while making efficient use of energy.

Application

SN74ACT1284PW is used in applications which require the ability to process and store data quickly and reliably. It is frequently used in conjunction with microcontrollers, allowing the microcontroller to quickly retrieve data from the SN74ACT1284PW\'s 16-bit memory bank. This allows for much faster data transmission and storage, as the microcontroller can access the data directly from the memory, rather than needing to spend time to receive and process the data from an external source. The SN74ACT1284PW is also frequently deployed in wireless communication applications, as it can provide a transmission media whereby signals sent from one device can be quickly stored and accessed.

Working Principle

The SN74ACT1284PW is a 16-bit shift register which uses flip-flops in four serial stages. Every two flip-flops form a basic shift-register stage, and the four stages of the SN74ACT1284PW are effectively four independent, yet interconnected, shift registers. The “ACT” in SN74ACT1284PW stands for the “active-low” design. This means that the device actively pulls the lines low to create a signal, rather than floating the lines high to form an open circuit. It is an important design feature, as it ensures the signal is properly transmitted with no risk of leakage. The device is designed to transfer signals using relatively low power, as well as create a number of built-in safeguards.

Conclusion

In summary, the SN74ACT1284PW is an important component for any application requiring reliable and accurate data transmission and storage. It is a workhorse that can be found in a variety of devices and applications, ranging from consumer electronics to industrial hardware. The active-low design of the device provides signal reliability, while the low power requirements mean that less energy is consumed when processing data. This makes the device ideal for any application that needs to store and transmit data quickly and reliably.
