The ADuM2250/ADuM22511 are hot swappable digital isolators with nonlatching， bidirectional communication channels that are compatible with I2 C interfaces. This eliminates the need for splitting I2 C signals into separate transmit and receive signals for use with standalone optocouplers. The ADuM2250 provides two bidirectional channels， supporting a complete isolated I2 C interface. The ADuM2251 provides one bidirectional channel and one unidirectional channel for those applications where a bidirectional clock is not required. The ADuM2250/ADuM2251 contain hot swap circuitry to prevent data glitches when an unpowered card is inserted onto an active bus. These isolators are based on iCoupler? chip scale transformer technology from Analog Devices， Inc. iCoupler is a magnetic isolation technology with performance， size， power consumption， and functional advantages compared to optocouplers. The ADuM2250/ADuM2251 integrate iCoupler channels with semiconductor circuitry to enable a complete， isolated I2 C interface in a small form factor package.
