Exact-Part Selection Insight
This device combines 4 isolated channels with 5000 Vrms isolation and 100Mbps maximum data rate. Channel direction, supply domains, PCB creepage/clearance and required working-voltage standard must be checked as a system; isolation-voltage headline value alone does not define the complete barrier design.
