The ADUM2251 series hot swappable Digital Isolators with non-latching, bidirectional communication channels. It is compatible with I²C interfaces. This eliminates the need for splitting I²C signals into separate transmit and receive signals for use with standalone optocouplers. The ADuM2251 provides one bidirectional channel and one unidirectional channel for those applications where a bidirectional clock is not required. It contains hot swap circuitry to prevent data glitches when an unpowered card is inserted onto an active bus. It is based on iCoupler® chip scale transformer technology from Analog Devices, Inc. iCoupler is a magnetic isolation technology with performance, size, power consumption and functional advantages compared to optocouplers. It integrates iCoupler channels with semiconductor circuitry to enable a complete, isolated I²C interface in a small form factor package.
● Open-drain interfaces
● Suitable for hot swap applications
● 30mA Current sink capability
● 1000kHz Operation
