The ADuM2250 are hot swappable digital isolators with nontlatching, 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 ADuM2250 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 integrate iCoupler channels with semiconductor circuitry to enable a complete, isolated I²C interface provided in a small form factor package.
