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.
