What is the advantage of the industrial version over the standard version?

The industrial version of the High Speed USB Isolator has following benefits:

• 2.5kV isolation, thus higher isolation resistance
• specified isolation working voltage
• extended temperature grade
• high retention connectors
• full specified and characterized parts, no substitutions allowed
• industrial-grade FPGAs with slightly better timing margin at room temperature
• each unit has to pass a safety isolation test with 2500Vrms for 2s
