基于74系列逻辑芯片的八路抢答器设计和改进

Design and Improvement of the Eight way Answer Device Based on 74 Series Logic Chip

阐述以74系列集成芯片为基础的改进的八路抢答器设计。在74系列集成芯片基础上实现使用较少的逻辑芯片显示数字“1,2,3,4,5,6,7,8”,解决了显示数字从“0”开始的问题。设计中利用74系列集成芯片性能稳定、功能强大、可靠性高、成本低等优点,在短时间内完成抢答识别功能。

This paper describes the design of an improved eight way answering device based on 74series integrated chips.On the basis of 74 series integrated chips,the digital display of "1,2,3,4,5,6,7,8" is realized by using fewer logic chips,which solves the problem of starting from "0".In the design,the advantages of 74 series integrated chips,such as stable performance,powerful functions,high reliability and low cost,are used to complete the function of quick response identification in a short time.
