Texas Instruments ISO7810 单通道数字隔离器

德州仪器 ISO7810 单通道数字隔离器是单通道数字隔离器，具有 8000V_PK 隔离电压。这些器件还通过了 VDE、CSA 和 CQC 增强隔离认证。每个隔离器均可提供很高的电磁抗扰性。这些隔离器在隔离 CMOS 或 LVCMOS 数字 I/O 的同时，有高抗电磁干扰性低辐射和低功耗。每个隔离通道的逻辑输入和输出缓冲器均由二氧化硅 (SiO₂) 绝缘隔栅分离开来。如果出现输入功率或信号损失，ISO7810 默认输出“高”电平，ISO7810F 默认输出“低”电平。当与隔离电源配合使用时，该器件可防止数据总线或其他电路上的噪声电流进入局部系统接地并干扰或损坏敏感电路。
