八路抢答器的设计与实现

Design and implementation of eight Responder

本文介绍了八路抢答器电路的设计、仿真及实现的全过程,提出两套可行的设计方案:方案一采用74ls373实现电路的锁存,74ls148实现电路的编码,采用74ls48及数码管实现电路的显示;方案二采用集锁存、译码、驱动电路为一体的CD4511集成电路及数码管实现抢答器的控制和显示。

The paper introduced the design,simulation and realization of the Eight-way Responder circuit,Two sets of feasible design scheme have been proposed :The first scheme,Latch circuitusing the chip of 74ls373,Encoding circuit using the chipof 74ls148,Display circuitusing the chip of 74ls48 and the Nixie tube;The secondscheme,The control circuit using the chip of CD4511,witch have the function forlatch, decoding and driving circuit;Display circuit using the Nixie tubedirectly.
