Texas Instruments ISO733x 低功耗三通道数字隔离器

德州仪器 ISO733x 低功耗三通道数字隔离器提供符合 UL 标准的长达 1 分钟高达 3000V_RMS 的电流隔离，以及符合 VDE 标准的 4242V_PK 的隔离。这些器件具有三个隔离通道，包括逻辑输入和输出缓冲器。由二氧化硅（SiO₂）绝缘隔栅分离开来。ISO7330 有三个同向通道，而 ISO7331 有两个正向通道和一个反向通道。为防止输入功率或信号损失，后缀为“F”的器件默认输出“低”电平，后缀没有“F”的器件则默认输出“高”电平。当与隔离电源配合使用时，这些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。
