3 Description

The ISO1640-Q1 (ISO164x-Q1) device is a hot swappable, low-power, bidirectional isolator that is compatible with I²C interfaces. The ISO164x supports UL 1577 isolation ratings of 5000 V_RMS in the 16-DW package, and 3000 V_RMS in the 8-D package. Each I²C 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 basic and reinforced insulation devices certified by VDE, UL, CSA, TUV and CQC. The ISO1640-Q1 has two isolated bidirectional channels for clock and data lines. ISO1640-Q1 integrates logic required to support bidirectional channels, providing a much simpler design and smaller footprint when compared to optocoupler-based solutions.
