... I eliminates the need for splitting I transmit and receive signals for use with standalone optocouplers. The ADuM2250 provides two bidirectional channels support- ing a complete isolated I one bidirectional channel and one unidirectional channel for those applications where a bidirectional clock is not required. ...
