Analog Devices ADuM4160 USB Digital Isolator is a USB port isolator based on iCoupler® technology. ADI ADuM4160 combines high-speed CMOS and monolithic air-core transformer technology to provide outstanding performance characteristics. The device is easily integrated with low and full speed USB-compatible peripheral devices. ADuM4160 provides mechanisms for detecting the direction of data flow and control over the state of the output buffers. Data direction is determined on a packet-by-packet basis.
