摘要
描述了工程师在将模拟开关和多路复用器设计到恶劣环境下所用模块中时面临的挑战,并提供了一些一般解决方案建议,以供电路设计人员用来保护容易损坏的器件。另外,介绍了一些新款集成开关和多路复用器,这些器件在过压保护、防闩锁特性和故障保护上均有所改善,能够处理常见应力状况。
This paper describes the challenges faced by engineers in designing analog switches and multiplexers to modules in harsh environments, and provides some general solutions for designers to protect vulnerable devices. In addition, some new integrated switches and multiplexers are introduced. These devices are improved in overvoltage protection, latch up protection and fault protection, which can handle common stress conditions.
