This eliminates the need for splitting I2C signals into separate transmit and receive signals for use with standalone 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 unpower...
