八路高速光电耦合器的研制

High Speed Optocoupler with Eight Channels

研制了一种独特的八路高速光电耦合器。器件采用混合集成电路方式,将24个芯片运用二次集成技术封装在20引线双列直插陶瓷管座中。设计中采用独立腔体分隔技术,将8个光路完全从物理上分离,彻底杜绝多路光信号间的相互干扰。文章重点描述了器件的结构特性、工作原理、参数设计以及特性曲线分析,并简要概括了在研制过程中采用的一些技术方法和制作工艺。

A new type of optocoupler high speed optocoupler with eight channels is introduced. The hybrid integrated circuit is used to seal 24 chips in the DIP20 dual in-line ceramic package. The avoidance of interferences betwee the multiplex signals is thoroughly resulted from the separation of eight channels each other. The structure characteristics, operation principle, parameter design and analysis of characteristic curve are mainly described, and some technology and fabrication in the process are explained in brief.
