The ISO644x 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 ISO644x devices provide high EMC performance while isolating CMOS or LVCMOS digital I/Os. ISO644x uses SiO2 as the isolation barrier. Each isolation channel has a logic input and output buffer separated by the insulation barrier. These devices come with enable pins that can be used to put the respective outputs in high impedance.
The ISO6440 and ISO6440F devices have all channels in the forward direction. The ISO6441 and ISO6441F devices have one reverse-direction channel. The ISO6442 and ISO6442F devices have two 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.
