onsemi NCID94xx High Speed Quad-Channel Digital Isolator
The onsemi NCID9401, NCID9411, NCID9400 and NCID9410 are galvanically isolated high-speed quad-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.
The digital isolators 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 NCID devices are housed in 16-pin wide body small outline packages.
