推挽输出与开漏输出的区别(zt)
Push- Pull输出就是一般所说的推挽输出，在CMOS电路里面应该较CMOS输出更合适，因为在CMOS里面的push－pull输出能力不可能做得双极那么大。输出能力看IC内部输出极N管P管的面积。和开漏输出相比，push－pull的高低电平由IC的电源低定，不能简单的做逻辑操作等。 push－pull是现在CMOS电路里面用得最多的输出级设计方式。
一.什么是OC、OD
集电极开路门(集电极开路 OC 或源极开路OD) open-drain是漏极开路输出的意思，相当于集电极开路(open-collector)输出，即ttl中的集电极开路（oc）输出。一 … … … … 阅读更多
我前一阵子写了一个基于SYSTEMC的单指令周期的8051IP核，所有指令测试通过，目前可以跑KEIL编译出来的rtx51程序，跑了4个任务，实现任务切换。
