热插拔双I2C总线隔离器5千伏adum2250/adum2251数据表

　　The ADuM2250/ADuM22511 are hot swappable digital isolators with nonlatching， bidirectional communication channels that are compatible with I2 C interfaces. This eliminates the need for splitting I2 C signals into separate transmit and receive signals for use with standalone optocouplers. The ADuM2250 provides two bidirectional channels， supporting a complete isolated I2 C interface. The ADuM2251 provides one bidirectional channel and one unidirectional channel for those applications where a bidirectional clock is not required. The ADuM2250/ADuM2251 contain hot swap circuitry to prevent data glitches 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 performance， size， power consumption， and functional advantages compared to optocouplers. The ADuM2250/ADuM2251 integrate iCoupler channels with semiconductor circuitry to enable a complete， isolated I2 C interface in a small form factor package.
