NCIx9211 Dual-Channel Digital Isolators

onsemi NCIx9211 Dual-Channel Digital Isolators are galvanically isolated full-duplex, bi-directional, high-speed dual-channel digital isolators with output enable. These devices support isolated communications, allowing digital signals to communicate between systems without conducting ground loops or hazardous voltages. The NCIx9211 utilizes the onsemi patented galvanic off-chip capacitor isolation technology and optimized IC design. The digital isolators achieve high insulation and high noise immunity, characterized by high common-mode rejection and power supply rejection specifications. The thick ceramic substrate yields capacitors with ~25 times the thickness of thin-film on-chip capacitors and coreless transformers. The result is a combination of the electrical performance benefits that digital isolators offer with the safety reliability of a >0.5mm insulator barrier similar to what optocouplers have historically offered. The onsemi NCIx9211 Dual-Channel Digital Isolators are housed in a 16-pin wide-body small outline package.
