onsemi NCID9210 two-way ceramic digital isolator-onsemi
ON Semiconductor NCID9210 bidirectional ceramic digital isolator is an electrically isolated full-duplex, bidirectional, high-speed dual-channel digital isolator in a 16-pin wide-body small-outline package.
NCID9210 supports isolated communication and transmits digital signals between systems without conducting ground loops and harmful voltages.
The NCID9210 bidirectional ceramic digital isolator adopts patented current off-chip capacitor isolation technology and optimized IC design to achieve high insulation and high noise immunity. These features have high common mode rejection and power supply rejection specifications.

The thickness of the capacitor produced by the thick ceramic substrate is approximately 25 times that of the thin-film on-chip capacitors and coreless transformers. Therefore, the electrical performance advantages provided by digital isolators are combined with the safety of >0.5mm insulator barriers (similar to the isolators traditionally provided by optocouplers).
