说明

ISOS141-SEP 抗辐射器件是采用小型 16 引脚 QSOP 封装的高性能四通道数字隔离器。每条隔离通道的逻辑输入和输出缓冲器均由双电容二氧化硅 (SiO2) 绝缘栅相隔离。该器件具有 100Mbps 的高数据速率、10.7ns 的低传播延迟和 4ns 的通道间严格偏移,支持近地轨道 (LEO) 航天应用。ISOS141-SEP 器件具有三个正向通道和一个反向通道,如果失去输入功率或信号,默认输出为低电平。使能引脚可用于将各输出置于高阻抗,适用于多主驱动应用,还可降低功耗。

ISOS141-SEP 在隔离 CMOS 或 LVCMOS 数字 I/O 时,具有高电磁抗扰度和低辐射、低功耗特性。该器件具有 100kV/µs 的高共模瞬态抗扰度,可轻松缓解系统级 ESD、EFT 和浪涌问题,还通过创新的芯片设计简化了辐射方面的合规性。
