Description

The NCID9211 is a galvanically isolated full duplex, bi?directional,

high?speed dual?channel digital isolator with output enable. This

device supports isolated communications thereby allowing digital

signals to communicate between systems without conducting ground

loops or hazardous voltages.

It utilizes onsemi’s patented galvanic off?chip capacitor isolation

technology and optimized IC design to 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 >0.5 mm insulator barrier similar to what has

historically been offered by optocouplers.

The device is housed in a 16?pin wide body small outline package.
