3 Description

The ISO644x devices are high-performance, quad-channel digital isolators designed for cost-sensitive applications requiring up to 5000VRMS isolation ratings per UL 1577. These devices are also certified by VDE, TUV, CSA, and CQC.

The ISO644x devices provide high electromagnetic immunity and low emissions at low power consumption 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 for parallel (multiple) control driving applications.

TheISO6441and ISO6441F 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.
