The ADuM1251ARZ-RL7 are hot swappable digital isolators with non-latching, 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.
The ADuM1251ARZ-RL7 provides one bidirectional channel and one unidirectional channel for those applications where a bidirectional clock is not required.
Both the ADuM1251ARZ-RL7 contain hot swap circuitry to prevent glitching data 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 as compared to optocouplers. With the ADuM1251ARZ-RL7, iCoupler channels can be integrated with semiconductor circuitry, which enables a complete isolated I2C interface to be implemented in a small form factor.
