故障安全系统中的大部分设计是为了检测和发现故障，引导系统输出安全信息。
The most part of the design in the Fail-safe system is to detect and discover faults, and lead the system to output safe information.
该接收器还支持开路、短路和终止(100)输入故障安全，在所有故障安全条件下，接收器输出为高电平。它采用易于进行PCB布局的直通式设计。
The receiver also supports open, shorted and terminated (100) input fail-safe and receiver output will be HIGH for all fail-safe conditions and it has a flow-through design for easy PCB layout.
