GENERAL DESCRIPTION

The ADuM1250/ADuM12511 are hot swappable digital isolators with nonlatching, bidirectional communication channels compatible with I2C® interfaces. This eliminates the need for splitting I2C signals into separate transmit and receive signals for use with standalone optocouplers.
