摘要
在电子专业技能训练课程中,74HC161是一种比较常见的同步可预置数四位二进制加法计数器集成块。无论在生活实际应用还是在教学过程中,若能正确理解和掌握74HC161集成块的逻辑功能,将有助于电路的装配、调试以及故障排除。因此,设计了一款方便操作、结构简便以及功能现象明显的74HC161逻辑功能测试电路。
In the electronic professional skill training courses,74HC161 is a common four bit binary addition counter integrated block with synchronous preset number.No matter in the practical application of life or in the teaching process,if we can correctly understand and master the logic function of 74HC161,it will be of great help to the assembly,debugging and troubleshooting of some common counting circuits composed of 74HC161.Based on years of practical teaching experience,the author designs the 74HC161 logic function test circuit which is easy to operate,simple in structure and obvious in function.
