The ADUM1250 series hot swappable dual Digital Isolator with non-latching, bidirectional communication channels that are compatible with I2C interfaces. This eliminates the need for splitting I2C signals into separate transmit and receive signals for use with standalone optocouplers. The ADuM1250 provides two bidirectional channels, supporting a complete isolated I2C interface. It contains hot swap circuitry to prevent glitching data when an unpowered card is inserted onto an active bus. It is based on the iCoupler? chip scale transformer technology from Analog Devices, Inc. iCoupler is a magnetic isolation technology with functional, performance, size and power consumption advantages as compared to optocouplers. With the isolator, iCoupler channels can be integrated with semiconductor circuitry, which enables a complete isolated I2C interface to be implemented in a small form factor.
