说明

、ISO1640 和 ISO1641 (ISO164x) 器件均为低功耗双向热插拔隔离器,低功耗双向热插拔隔离器,兼容 I2C 接口。ISO164x 符合 UL 1577 标准,采用 16-DW 封装时支持 5000VRMS 隔离等级,而采用 8-D 封装时支持 3000 VRMS 隔离等级。该低辐射器件的每条隔离通道都具有通过双电容二氧化硅 (SiO2) 绝缘栅实现隔离的逻辑输入和开漏输出。该系列包含的基础和增强型隔离等级器件已通过 VDE、UL、CSA、TUV 和 CQC 认证。The ISO1640 具有两条隔离式双向通道,分别应用于时钟和数据线,而 ISO1641 具有一条双向数据通道和一条单向时钟通道ISO164x 系列集成了支持双向通道所需的逻辑,与基于光耦合器的解决方案相比,设计更加简化,尺寸更小。
