GENERAL DESCRIPTION
The ADuM1250/ADuM1251¹ are hot swappable digital isolators with nonlatching, 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. The ADuM1251 provides one bidirectional channel and one unidirectional channel for applications where a bidirectional clock is not required. 

Both the ADuM1250 and the ADuM1251 contain hot swap circuitry to prevent glitching data when an unpowered card is inserted onto an active bus.
These isolators are 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 ADuM1250/ADuM1251, iCoupler channels can be
integrated with semiconductor circuitry, which enables a complete isolated I²C interface to be implemented in a small form factor.
