The ADuM260N/ADuM261N/ADuM262N/ADuM263N1 are
6-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 maxi-
mum propagation delay is 13 ns with a pulse width distortion of
less than 4.5 ns at 5 V operation. Channel to channel matching
of propagation delay is tight at 4.0 ns maximum.

The ADuM260N/ADuM261N/ADuM262N/ADuM263N 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 1.7 V to 5.5 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 predeter-
mined state when the input power supply is not applied.
