3 Description

The ISO646x devices are general purpose digital isolators designed for applications requiring up to 5000VRMS isolation rating per UL 1577. The devices are also certified by VDE, TUV, CSA, and CQC.

The ISO646x devices provide high EMC performance while isolating CMOS or LVCMOS digital I/Os. ISO646x uses SiO2 as the isolation barrier. Each isolation channel has a logic input and output buffer separated by the insulation barrier.

The ISO6460 and ISO6460F devices have all channels in the forward direction. TheISO6461and ISO6461F devices have one reverse-direction channel.The ISO6462 and ISO6462F devices have two reverse-direction channels. The ISO6463 and ISO6463F devices have three reverse-direction channels.

In the event of input power or signal loss, the default output is high for devices without the suffix F and low for devices with the suffix F. See the Device Functional Modes section for further details.
