The ADuM230D/ADuM230E/ADuM231D/ADuM231E1 are
triple-channel digital isolators based on Analog Devices, Inc.,
iCoupler® technology. Combining high speed, complementary
metal-oxide semiconductor (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. The
maximum propagation delay is 13 ns with a pulse width
distortion of less than 3 ns at 5 V operation. Channel matching
is tight at 3.0 ns maximum.

Unlike other optocoupler alternatives, dc correctness is ensured
in the absence of input logic transitions. Two different fail-safe
options are available, by which the outputs transition to a
predetermined state when the input power supply is not applied
or the inputs are disabled.
The ADuM230D/ADuM230E/ADuM231D/ADuM231E data
channels are independent and are available in a variety of
configurations with a withstand voltage rating of 5.0 kV rms
(see the Ordering Guide). The devices operate with the supply
voltage on either side ranging from 1.8 V to 5 V, providing
compatibility with lower voltage systems as well as enabling
voltage translation functionality across the isolation barrier.
