ISO164x/ISO164x-Q1 Digital Isolators

Texas Instruments ISO164x/ISO164x-Q1 Bi-Directional I2C Digital Isolators are hot-swappable, low-power, bidirectional isolators compatible with I2C interfaces. This digital isolator supports UL 1577 isolation ratings of 3000VRMS 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 Texas Instruments ISO164x/ISO164x-Q1 has two isolated bidirectional channels for clock and data lines. ISO164x/ISO164x-Q1 integrates logic required to support bidirectional channels, providing a much simpler design and smaller footprint when compared to optocoupler-based solutions. The ISO164x-Q1 devices are AEC-Q100 qualified for automotive applications.
