Description:

The ISO776x-Q1 devices are high-performance, six-channel digital isolators with 5000VRMS (DW package) and 3000VRMS (DBQ package) isolation ratings per UL 1577. This family of devices is also VDE, CSA, TUV, and CQC certified. While isolating CMOS or LVCMOS digital I/Os, the ISO776x-Q1 family of devices provide high electromagnetic immunity and low emissions at low power consumption. Each isolation channel has a logic input and output buffer separated by a silicon dioxide (SiO2) insulation barrier. The ISO776x-Q1 family of devices is available in all possible pin configurations such that all six channels can be in the same direction, or one, two, or three channels can be in reverse direction while the remaining channels are in the forward direction. In case of input power or signal loss, the devices without the F suffix default to a high output, while devices with the F suffix default to a low output. For more details, refer to the Device Functional Modes section.
