Description
The NCID9210 and NCID9216 are galvanically isolated full
duplex, bi−directional, high−speed dual−channel digital isolators.
These devices support isolated communications thereby allowing
digital signals to communicate between systems without conducting
ground loops or hazardous voltages.
They utilize 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.
