集成电路仅仅用了半个世纪就变得无处不在，现代社会结构已经离不开计算机，手机和其他数字电器。这是因为，集成电路是现代计算，交流，制造和交通系统，包括互联网都必不可少的东西。集成电路带来的数字革命会给人类社会带来巨大的变化已成为许多学者的共识。
数据选择器是一种中规模集成器件, 广泛地使用在各种各样的数字集成电路中，利用数据选择器设计的组合逻辑电路真的很有利用价值, 通过提高电路的设计水平能解决常规门电路设计中存在的问题[2]。数据选择器是一种具有多种用途的逻辑部件，除了可以实现一些组合逻辑设计外，还可用实现多通道传输电路、生成序列码以及比较器等。
本文通过研究八选一数据选择器74LS151的原理和功能，发掘出它的特点，更好的研究和利用它，只有对它研究通透，才能发明更多对社会发展进步有利的东西。

Abstract
Electronic technology is a new technology developed in the last century began, 1958 the first samples of integrated circuits found in the world. Electronic technologies have reached a new stage of development was due to the emergence of integrated circuits and applications. Into modern society, people are facing information society, marked by micro-electronics to computers and the Internet. Social productive forces and economic boom thanks to the extensive application of high technology. Modern electronic technology, communications, science, technology and industry for national defense, and life and culture and other fields have played a huge role.
IC merely half a century, became ubiquitous, the modern social structure has been inseparable from the computer, mobile phone and other digital appliances. This is because the circuit is a modern computing, communication, manufacturing and transport systems, including the Internet, are indispensable things. IC brings the digital revolution will bring great changes to human society has become the consensus of many scholars.
Data Selector is a medium-scale integration devices, is widely used in digital integrated circuits, combinational logic circuit design using data selector is useful, by improving the level of circuit design can solve the problems in conventional circuit design. Data Selector is a multiple-use logic, in addition to being able to implement some Combinatorial logic design, also available for multi-channel transmission circuits, generate a sequence of code, such as comparators.
Based on eight selected data selector 74LS151 principles and functions to explore its features, better research and make use of it, just study it fully, to invent something more beneficial to social development and progress.
