摘　　要：单片机接口技术在很多文献中均有详细的介绍,但在对大量电气控制产品的改造和设计中,经常会碰到用接口芯片所无法解决的问题(如驱动电流大、开关速度慢、抗干扰差等),因此必须寻求另一种电路解决方案。分析几种输入/输出电路通过广泛的应用表明,其对合理、可靠地实现单片机电气控制系统具有较高的工程实用价值。MCU interface technology in many documents was introduced in detail. But in the design and modification of a large number of electric products, we often find that the interface chip can not solve the problem, such as driving current, switching speed, poor anti-interference etc. Therefore, we must get another circuit solutions. Analysis of several input or output circuits shows that it has high practical value for the reasonable and reliable realization of single chip microcomputer in electrical control system.
