GENERAL DESCRIPTION
The ADuM140D/ADuM140E/ADuM141D/ADuM141E/
ADuM142D/ADuM142E1 are quad-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.
The ADuM140D/ADuM140E/ADuM141D/ADuM141E/
ADuM142D/ADuM142E data channels are independent and
are available in a variety of configurations with a withstand
voltage rating of 3.0 kV rms or 3.75 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.

Figure 3. ADuM142D/ADuM142E Functional Block Diagram
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 pre-
determined state when the input power supply is not applied or the
inputs are disabled. The ADuM140E1/ADuM141E1/ADuM142E1
are pin-compatible with the ADuM1400/ADuM1401/ADuM1402.
