GENERAL DESCRIPTION
The ADuM2250/ADuM2251
isolators with nonlatching bidirectional communication
channels that are compatible with I
eliminates the need for splitting I
transmit and receive signals for use with standalone
optocouplers.
The ADuM2250 provides two bidirectional channels support-
ing a complete isolated I
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 consump-
tion, and functional advantages compared to optocouplers.
The ADuM2250/ADuM2251 integrate iCoupler channels
with semiconductor circuitry to enable a complete, isolated
I
