ADUM2251 (ADUM2250 / ADUM2251) Dual I2C Isolators

The ADuM2250/ADuM22511 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 ADuM2250 provides two bidirectional channels, supporting a complete i.
