摘要
双向移位寄存器是一种中规模集成电路,可构成移位寄存器型计数器。文中介绍了双向移位寄存器的功能,以及由其构成的环形移位计数器的电路结构和输出状态。设计并论述了由环形移位计数器控制的单灯单向和双灯反向两种彩灯控制电路,说明对于较简单的彩灯控制要求,可以实现结构简单、稳定可靠、经济适用的控制电路。
Bidirectional shift register is a kind of medium-scale integrated circuits used as the components of various counters. This paper introduces the basic functions of bidirectional shift register and circuit construction and output states of ring shift counter composited by bidirectional shift register; then designs and discusses two kinds of lights circuits controlled by ring shift counters; and finally indicates that the designed control circuits, with the advantages of simple structure, stable function and low cost, can meet relatively simple control demands.
