The ISO642x 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 ISO642x devices provide high EMC performance while isolating CMOS or LVCMOS digital I/Os. ISO642x uses SiO2 as the isolation barrier. Each isolation channel has a logic input and output buffer separated by the insulation barrier.
The ISO6420 and ISO6420F devices have all channels in the forward direction. The ISO6421 and ISO6421F devices have one reverse-direction channel.
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.
