描述
The ISO1640 (ISO164x) device is a hot swappable, low-power, bidirectional isolator that is compatible with I2C interfaces. This digital isolator supports UL 1577 isolation ratings of 3000 VRMS in the 8-D package. Each isolation channel in this low emissions device has a logic input and open drain output separated by a double capacitive silicon dioxide (SiO2) insulation barrier. This family includes devices certified by VDE, UL, CSA, TUV and CQC. The ISO1640 has two isolated bidirectional channels for clock and data lines. ISO1640 integrates logic required to support bidirectional channels, providing a much simpler design and smaller footprint when compared to optocoupler-based solutions.
