High Speed Dual-Channel, Bi-Directional Ceramic Digital Isolator

The NCID9210 and NCID9216 are galvanically isolated fullduplex, bi−directional, high−speed dual−channel digital isolators.These devices support isolated communications thereby allowingdigital signals to communicate between systems without conductingground loops or hazardous voltages.They utilize onsemi patented galvanic off−chipcapacitor isolation technology and optimized IC design to achievehigh insulation and high noise immunity, characterized by highcommon mode rejection and power supply rejection specifications.The thick ceramic substrate yields capacitors with ~25 times thethickness of thin film on−chip capacitors and coreless transformers.The result is a combination of the electrical performance benefits thatdigital isolators offer with the safety reliability of a >0.5 mm insulatorbarrier similar to what has historically been offered by optocouplers.The device is housed in a 16−pin wide body small outline package.
