用万用表。测量。要熟悉每个芯片引脚的功能。先在芯片找到时钟。锁存，数据位置。然后找到ABCD的位置。最后找到OE的位置。向上测量。反推即可

请问师傅，时钟，锁存，数据位置都有了。abcd是什么意思？怎么找？
CD4094 位移位存储总线寄存器: CD4094是带输出锁存和三态控制的串入/并出高速转换器，具有使用简单、功耗低、驱动能力强和控制灵活等优点。 CD4094的引脚定义如图1。其中(1)脚为锁存端，(2)脚为串行数据输入端，(3)脚为串行时钟端。(1)脚为高电平时，8位并行输出口Q1～Q8在时钟的上升沿随串行输入而变化；(1)脚为低电平时，输出锁定。利用锁存端可方便地进行片选和级联输出控制。(15)脚为并行输出状态控制端，(15)脚为低电平时，并行输出端处在高阻状态，在用CD4094作显示输出时，可使显示数码闪烁。(9)脚QS、(10)脚Q′S是串行数据输出端，用于级联。QS端在第9个串行时钟的上升沿开始输出，Q′S端在第9个串行时钟的下降沿开始输出。838电子当CD4094电源为5V时，输出电流大于3．2MA，灌电流为1 MA。串行时钟

A B C D就是行扫。找到行扫芯片。138.然后查找对应的引脚

只要不是研究。老卡建议扔掉。。。那个功夫比东西值钱
