讯享网<span>广东清远矿用光缆MGXTSV-36B广东清远实际上很多时候我们并不需要知道集成块内部电路组成情况，只需了解外部各引脚的功能即可。集成电路各引脚的功能用文字加以注明，如电路中没给出文字说明或参数，则应查阅有关手册，了解集成块的逻辑功能和各引脚的作用。对一些常用的集成电路，如常用的LM324运算放大器、74LS00四二输入与非门、555时基电路等，读者应记住各引脚的功能，这对快速、准确识图有所帮助。和分别为74LS00、CH7555的引脚图。74LS00引脚图CH7555引脚图功能看模块对数字电路可按信号流向把系统分成若干个功能模块，每个模块完成相对独立的功能，对模块进行互操作状态分析，必要时可列出各模块的输入、输出逻辑真值表。<br />
