GENERAL DESCRIPTION
The ADuM120N/ADuM121N1 are dual-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 ADuM120N/ADuM121N data channels are independent and
are available in a variety of configurations with a withstand voltage
rating of 3 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 in which the outputs transition to a predetermined
state when the input power supply is not applied or the inputs
are disabled.
The ADuM120N0 is pin-compatible with the ADuM1285, and
the ADuM120N1 is pin-compatible with the ADuM1280 and
the ADuM1200. The ADuM121N0 is pin-compatible with
ADuM1286, and the ADuM121N1 is pin-compatible with the
ADuM1281 and the ADuM1201.

ADuM120N/ADuM121N
ELECTRICAL CHARACTERISTICS—3.3 V OPERATION
All typical specifications are at TA = 25°C, VDD1 = VDD2 = 3.3 V. Minimum/maximum specifications apply over the entire recommended
operation range: 3.0 V ≤ VDD1 ≤ 3.6 V, 3.0 V ≤ VDD2 ≤ 3.6 V, and −40°C ≤ TA ≤ +125°C, unless otherwise noted. Switching specifications
are tested with CL = 15 pF and CMOS signal levels, unless otherwise noted. Supply currents are specified with 50% duty cycle signals.
