DATA SHEET www.onsemi.com High Speed Quad-Channel Digital Isolator NCID9401, NCID9411, NCID9400, NCID9410 SOIC16 W CASE 751EN Description The NCID9401, NCID9411, NCID9400 and NCID9410 are MARKING DIAGRAM galvanically isolated highspeed quadchannel 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. ON AWLYWW It utilizes onsemis patented galvanic offchip capacitor isolation 94xx 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 onchip capacitors and coreless transformers. The result is a combination of A = Assembly Location the electrical performance benefits that digital isolators offer with the WL = Wafer Lot / Assembly Lot safety reliability of a >0.5 mm insulator barrier similar to what has Y = Year WW = Work Week historically been offered by optocouplers. xx = 00, 01, 10, 11 The device is housed in a 16pin wide body small outline package.
