GENERAL DESCRIPTION
The ADuM240D/ADuM240E/ADuM241D/ADuM241E/
ADuM242D/ADuM242E
1
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 ADuM240D/ADuM240E/ADuM241D/ADuM241E/
ADuM242D/ADuM242E 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.
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 ADuM240E1/ADuM241E1/ ADuM242E1 are pin
compatible with the ADuM2400/ ADuM2401/ADuM2402.
