The ADuM1251ARZ 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 provides one bidirectional channel and one unidirectional channel for those applications where a bidirectional clock is not required.
Both the ADuM1251ARZ 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, iCoupler channels can be integrated with semiconductor circuitry, which enables a complete isolated I2C interface to be implemented in a small form factor.
