Data Sheet  
ADuM240D/ADuM240E/ADuM241D/ADuM241E/ADuM242D/ADuM242E  
THEORY OF OPERATION  
The ADuM240D/ADuM240E/ADuM241D/ADuM241E/  
ADuM242D/ADuM242E use a high frequency carrier to  
transmit data across the isolation barrier using iCoupler chip  
scale transformer coils separated by layers of polyimide isolation.  
Using an on/off keying (OOK) technique and the differential  
architecture shown in Figure 19 and Figure 20, the ADuM240D/  
ADuM240E/ADuM241D/ADuM241E/ADuM242D/ADuM242E  
have very low propagation delay and high speed. Internal regulators  
and input/output design techniques allow logic and supply  
voltages over a wide range from 1.7 V to 5.5 V, offering voltage  
translation of 1.8 V, 2.5 V, 3.3 V, and 5 V logic. The architecture  
is designed for high common-mode transient immunity and  
high immunity to electrical noise and magnetic interference.  
Radiated emissions are minimized with a spread spectrum  
OOK carrier and other techniques.  
Figure 19 illustrates the waveforms for models of the ADuM240D/  
ADuM240E/ADuM241D/ADuM241E/ADuM242D/ADuM242E  
that have the condition of the fail-safe output state equal to low,  
where the carrier waveform is off when the input state is low.  
If the input side is off or not operating, the low fail-safe output  
state (ADuM240D0/ADuM240E0/ADuM241D0/ADuM241E0/  
ADuM242D0/ADuM242E0) sets the output to low. For the  
ADuM240D/ADuM240E/ADuM241D/ADuM241E/ADuM242D/  
ADuM242E that have a high fail-safe output state, Figure 20  
illustrates the conditions where the carrier waveform is off  
when the input state is high. When the input side is off or not  
operating, the high fail-safe output state (ADuM240D1/  
ADuM240E1/ADuM241D1/ADuM241E1/ADuM242D1/  
ADuM242E1) sets the output to high. See the Ordering Guide  
for the model numbers that have the fail-safe output state of low  
or the fail-safe output state of high.
