| 摘 要： | 利用半导体器件允许瞬态过载的特性对数字器件进行在线故障隔离和诊断是一种实用性强的故障诊断方法。通过实验对TTL器件的过驱动特性进行了研究,得出了TTL器件的过驱动特性曲线,并从微观粒子运动的角度对曲线的本质进行了解释。该实验结果为设计基于反向驱动的数字电路故障诊断系统提供了有力的依据。

| Abstract: | It is a practical method to use the characteristic of twinkle-over-loading of semiconductor component to isolate and diagnosis digital components in-circuits.The characteristic of twinkle-over-loading of TTL component is studied by experiment,it's curve of over-drive is obtained and the reason is explained in the movement of micro-electronics.A strong backup of design digital circuit fault diagnosis system based on over-drive is given. |
