The ADuM2250 / ADuM2251 are hot swappable digital isolators with non-latching, bidirectional communication channels and are compatible with I2C interfaces. This eliminates the need for splitting I2C signals into separate transmit and receive signals for use with stand-alone optocouplers.The ADuM2250 provides two bidirectional channels, supporting a complete isolated I2C 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 functional, performance, size, and power consumption advantages compared to optocouplers. The ADuM2250 / ADuM2251 integrate iCoupler channels with semiconductor circuitry to enable a complete, isolated I2C interface provided in a small form factor.APPLICATIONS Isolated I2C, SMbus, or PMBus Interfaces Multilevel I2C interfaces Power supplies Networking Power over Ethernet
