GENERAL DESCRIPTION  
The ADuM1280/ADuM1281/ADuM1285/ADuM12861 are dual-  
channel digital isolators based on the Analog Devices, Inc.,  
iCoupler® technology. Combining high speed CMOS and  
monolithic air core transformer technology, these isolation  
components provide outstanding performance characteristics  
superior to alternatives, such as optocoupler devices and other  
integrated couplers.  
either side ranging from 3.135 V to 5.5 V and the automotive  
grades operate from 3.135 V to 5.5 V, providing compatibility  
with lower voltage systems as well as enabling a voltage  
translation functionality across the isolation barrier. Unlike  
other optocoupler alternatives, the ADuM1280/ADuM1281/  
ADuM1285/ADuM1286 isolators have a patented refresh  
feature that ensures dc correctness in the absence of input logic  
transitions. When power is first applied or is not yet applied to  
the input side, the ADuM1280 and ADuM1281 have a default  
high output, and the ADuM1285 and ADuM1286 have a default  
low output.  
With propagation delay at 23 ns, pulse width distortion is less  
than 2 ns for C grade. Channel-to-channel matching is tight at  
5 ns for C grade. The two channels of the ADuM1280/ADuM1281/  
ADuM1285/ADuM1286 are independent isolation channels  
and are available in two channel configurations with three  
different data rates up to 100 Mbps (see the Ordering Guide).  
Industrial grade models operate with the supply voltage on
