This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.

ON SEMICONDUCTOR NCID9211 Dual-Channel Digital Isolator

ON Semiconductor NCID9211 Dual-Channel Digital Isolators combine the performance of conventional digital isolators with insulation reliability similar to optocouplers. 

This is made possible by ON Semiconductor’s patented galvanic off-chip capacitor isolation technology and a thick ceramic substrate, which provides a 2000VPEAK maximum working insulation voltage and an insulation barrier >0.5mm. The isolators are capable of full duplex, bi-directional communication with data rates up to 50Mbps and with output enable functions on the primary and secondary sides. 

The NCID9211 offer high common mode rejection and performance is guaranteed with a 2.5V to 5.5V supply at temperatures up to 125°C. They also offer 8mm creepage and clearance and are housed in a wide body, 16-lead SOIC package.
