Logic is a central part of computing and embedded systems, acting as a connection between digital and analog components and devices. Buffers, Drivers, Receivers, and Transceivers are necessary devices for ensuring signals, data, and power can travel in the right direction and are properly interpreted by different systems. Understanding the application field and working principle of these devices is essential in order to utilize them in a project. This article will discuss the application field and working principle of the 74ABT651PW,112, an 8-bit multiplexer/demultiplexer: its primary function, user applications, internal circuits, and more.

What is 74ABT651PW,112?

The 74ABT651PW,112 is an 8-bit multiplexer/demultiplexer logic device. Multiplexers are devices that are used to "multiplex" multiple digital signals into one or two data lines, while demultiplexers are used to take one or two data lines and convert them into multiple digital signals. This device is designed to perform both functions simultaneously.

Application

The 74ABT651PW,112 has a wide variety of uses in digital systems, embedded systems, and digital structured data processing systems. It is commonly used for data transfer, communication, and digital signal processing.

In digital systems, the 74ABT651PW,112 is used as a multiplexer/demultiplexer, allowing different signals to be transferred quickly between different components. In communications, it is used to allow data to be transmitted and received over different mediums, such as telephone lines or radio. In digital structured data processing systems, it can be used to send data to different parts of a system, or to connect different components for a specific purpose.

Internal Circuit

The 74ABT651PW,112 is made up of two distinct logic circuits. The first is an 8-bit multiplexer circuit. This circuit has eight data inputs, four select lines, and two outputs. The second circuit is an 8-bit demultiplexer circuit. This circuit takes one data input and four select lines, and produces eight outputs.

The multiplexer circuit takes the eight input bits and uses the four select lines to determine which of the input bits should be outputted on the two output lines. The select lines can be used to specify the combination of input bits that should be outputted on the two outputs. The demultiplexer circuit works in reverse. It takes one input bit and the four select lines and outputs different combinations of bits on the eight output lines. The select lines can be used to specify which bits should be outputted on each of the eight outputs.

Features & Advantages

The 74ABT651PW,112 has several features and advantages that make it a desirable part for many applications. Firstly, it is a single-package device, meaning all of its components are contained within a single IC package. This makes it easier to install and manage, as well as more cost-effective than using multiple individual components. Additionally, it is very power efficient, with a low operating voltage of 3.3V, and a maximum power consumption of only 7.5µA.

The 74ABT651PW,112 also features advanced level shifting capabilities and wide threshold logicoutputs. The level shifting capability allows the device to work with different logic levels without requiring external voltage sources. The wide threshold logic outputs allow it to be used with both CMOS and TTL devices. Additionally, this device also has very low propagation delay times, meaning that it is well-suited for use in high-speed applications.

Conclusion

The 74ABT651PW,112 is an excellent choice for many applications where multiplexing or demultiplexing is necessary. With its low power consumption, advanced level shifting capabilities, and wide threshold logic outputs, it can be used in a wide variety of projects. Its single-package design also makes it more cost-effective and easier to install than using multiple individual components, making it an ideal device for many digital systems, embedded systems, and digital structured data processing systems.
