Overview
The ADUM2250ARIZ-RL from Analog Devices Inc. is a hot-swappable digital isolator designed to provide nonlatching, bidirectional communication channels compatible with I²C interfaces. This component eliminates the need for splitting I²C signals into separate transmit and receive signals, making it ideal for applications requiring isolated I²C, SMBus, or PMBus interfaces. The ADUM2250ARIZ-RL features two bidirectional channels, supporting a completely isolated I²C interface, and includes hot swap circuitry to prevent data glitches when an unpowered card is inserted into an active bus.
