![]() ![]() The ISO1640-Q1 has two isolated bidirectional channels for clock and data lines. This family includes basic and reinforced insulation devices certified by VDE, UL, CSA, TUV and CQC. Each I 2C isolation channel in this low emissions device has a logic input and open drain output separated by a double capacitive silicon dioxide (SiO 2) insulation barrier. 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. The ISO1640-Q1 (ISO164x-Q1) device is a hot swappable, low-power, bidirectional isolator that is compatible with I 2C interfaces.
