Triple-Channel Digital Isolators
GENERAL DESCRIPTION
The
1
are triple-channel digital isolators
based on the Analog Devices, Inc.,
iCoupler®
technology.
Combining high speed CMOS and monolithic transformer
technology, these isolation components provide outstanding
performance characteristics superior to alternatives, such as
optocouplers.
By avoiding the use of LEDs and photodiodes,
iCoupler
devices remove the design difficulties commonly associated
with optocouplers. The typical optocoupler concerns regarding
uncertain current transfer ratios, nonlinear transfer functions, and
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 consume one-tenth to one-sixth of the power of
optocouplers at comparable signal data rates.
The
isolators provide three independent
isolation channels in a variety of channel configurations and
data rates (see the Ordering Guide). Both 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 a voltage translation functionality across the isolation
barrier. In addition, the
provide low
pulse width distortion (<2 ns for CRW grade) and tight channel-
to-channel matching (<2 ns for CRW grade). Unlike other
optocoupler alternatives, the
isolators
have a patented refresh feature that ensures dc correctness in the
absence of input logic transitions and when power is not applied
to one of the supplies.
