Analog Devices / Maxim Integrated MAX14933/MAX14937 双通道 I2C 隔离器
Maxim MAX14933/MAX14937 双通道 I2C 隔离器是采用 Maxim 专有工艺技术的两通道 2.75kVRMS 或 5kVRMS I2C 数字隔离器。 每个器件在电路之间传输数字信号，具有不同的电源域，环境温度高达 +125°C。这些器件为要求在同一线路上两个方向传输数据的 I2C 等应用提供两个双方向开漏通道。 每个器件均在隔离器两侧采用独立的 2.25V 至 5.5V 电源。 这些隔离器在直流至 1.7MHz 运行，可用于带时钟扩展的隔离式 I2C 总线。
The Analog Devices MAX14933 and MAX14937 2-Channel I2C Isolators is available in wide-body and narrow-body SOIC-16 packages. The MAX14937 is available in a wide-body SOIC-16 package. Both devices are rated for operation at ambient temperatures of -40°C to +125°C.
