3 Description

The ISO644x devices are high-performance, quadchannel

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.

The ISO6441 and 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.
