Shenzhen Meiyuxin Technology Co., Ltd [ADI agent] brand new original ADUM2251ARWZ digital isolator Hot Swappable Dual I2C Isolator, 5kV! ! !

GENERAL DESCRIPTION

ADUM2251ARWZ 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.

ADUM2251ARWZ  provides two bidirectional channels, supporting a complete isolated I2C interface. The ADuM2251 provides one bidirectional channel and one unidirectional channel for those applications where a bidirectional clock is not required.

ADUM2251ARWZ  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 iCoupler is a magnetic isolation technology with performance, size, power consumption, and functional advantages compared to optocouplers. ADUM2251ARWZ  integrate iCoupler channels with semiconductor circuitry to enable a complete, isolated I2C interface in a small form factor package
