內(nèi)容摘要：
本設(shè)計(jì)將采用幾個(gè)基本的數(shù)字集成的74系列（74LS90,74LS153,555）芯片來(lái)完成所需要的數(shù)字邏輯顯示功能（在七段數(shù)碼管上按規(guī)律顯示特定的數(shù)字）。我們將通過(guò)幾個(gè)方案的對(duì)比，得出本方案的優(yōu)越性。本設(shè)計(jì)具有邏輯清晰、設(shè)計(jì)巧妙的特點(diǎn)，能很好的符合《數(shù)字電子技術(shù)》課程設(shè)計(jì)的要求。

Contents summary
The design will use a few basic digital compositive (74 Series) CMOS chip to accomplish the demanded digital logical display function (According to the rule to display the given numbers on the seven-sect numeral-pipe ).We will get the superiority by comparing with several project. There are several excellent point in this design, such as it’s logic is very legible and it’s design is smart ,and it can accord with the demand of 《Digital Electronic Technology 》 very well.

Key words：74 Series CMOS chip, Digital logic，Design
