GENERAL DESCRIPTION
The ADuM141x
Analog Devices, Inc. iCoupler® technology. Combining high
speed CMOS and monolithic air core transformer technologies,
these isolation components provide outstanding performance
characteristics superior to alternatives such as optocoupler devices.
By avoiding the use of LEDs and photodiodes, iCoupler devices
remove the design difficulties commonly associated with opto-
couplers. The usual concerns that arise with optocouplers, such
as uncertain current transfer ratios, nonlinear transfer functions,
and temperature and lifetime effects are eliminated with the
simple iCoupler digital interfaces and stable performance charac-
teristics. The need for external drivers and other discrete
components is eliminated with these iCoupler products.

Furthermore, iCoupler devices consume one-tenth to one-sixth
the power of optocouplers at comparable signal data rates.
The ADuM141x isolators provide four independent isolation
channels in a variety of channel configurations and data rates
(see the Ordering Guide) up to 10 Mbps. All models operate
with the supply voltage on either side ranging from 2.7 V to 5.5 V,
providing compatibility with lower voltage systems as well as
enabling voltage translation functionality across the isolation
barrier. All products also have a default output control pin. This
allows the user to define the logic state the outputs are to adopt
in the absence of the input power. Unlike other optocoupler
alternatives, the ADuM141x isolators have a patented refresh
feature that ensures dc correctness in the absence of input logic
transitions and during power-up/power-down conditions.
