temperature and lifetime effects are eliminated with the simple  
iCoupler digital interfaces and stable performance  
characteristics. The need for external drivers and other discrete  
components is eliminated with these iCoupler products.  
Furthermore, iCoupler devices run at one-tenth to one-sixth  
the power of optocouplers at comparable signal data rates.

The ADuM221x isolators provide two independent isolation  
channels in a variety of channel configurations and data rates  
(see the Ordering Guide). The ADuM221x models operate with  
the supply voltage of either side ranging from 3.0 V to 5.5 V,  
providing compatibility with lower voltage systems as well as  
enabling voltage translation functionality across the isolation  
barrier. The ADuM221x isolators have a patented refresh feature  
that ensures dc correctness in the absence of input logic transi-  
tions and during power-up/power-down conditions.  
APPLICATIONS  
General-purpose, high voltage, multichannel isolation  
Medical equipment  
Power supplies  
RS-232/RS-422/RS-485 transceiver isolation  
GENERAL DESCRIPTION  
The ADuM221x1 are 2-channel digital isolators based on Analog  
Devices, Inc., iCoupler® technology. Combining high speed CMOS  
and monolithic air core transformer technology, these isolation  
components provide outstanding performance characteristics that  
are superior to alternatives such as optocoupler devices.  
Similar to the ADuM320x isolators, the ADuM221x isolators con-  
tain various circuit and layout enhancements to provide increased  
capability relative to system-level IEC 61000-4-x testing (ESD,  
burst, and surge). The precise capability in these tests for either  
the ADuM320x or ADuM221x products is strongly determined by  
the design and layout of the users board or module. For more  
information, see the AN-793 Application Note, ESD/Latch-Up  
Considerations with iCoupler Isolation Products.  
By avoiding the use of LEDs and photodiodes, iCoupler devices  
remove the design difficulties commonly associated with opto-  
couplers. Typical optocoupler concerns regarding uncertain  
current transfer ratios, nonlinear transfer functions, and
