High Speed Dual-Channel,
Bi-Directional Ceramic
Digital Isolator
SOIC16 W
CASE 751EN
NCID9211
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.
