Product Summary

The ADUM1251ARZ is hot swappable digital isolator with non latching bidirectional communication channels compatible with I2C interfaces. The device 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 glitching data when an unpowered card is inserted onto an active bus.
