Triple-Channel, Digital Isolators,
Enhanced System-Level ESD Reliability
Data Sheet
ADuM3300/ADuM3301
FEATURES GENERAL DESCRIPTION
Enhanced system-level ESD performance per IEC 61000-4-x 1
The ADuM3300/ADuM3301 are 3-channel digital isolators based
Low power operation
on the Analog Devices, Inc., iCoupler technology. Combining
5 V operation
high speed CMOS and monolithic air core transformer technology,
2.0 mA per channel maximum at 0 Mbps to 2 Mbps
these isolation components provide outstanding performance
4.1 mA per channel maximum at 10 Mbps
characteristics superior to alternatives, such as optocoupler devices.
36 mA per channel maximum at 90 Mbps
iCoupler devices remove the design difficulties commonly
3.3 V operation
associated with optocouplers. Typical optocoupler concerns
1.0 mA per channel maximum at 0 Mbps to 2 Mbps
regarding uncertain current transfer ratios, nonlinear transfer
2.8 mA per channel maximum at 10 Mbps
functions, and temperature and lifetime effects are eliminated
17 mA per channel maximum at 90 Mbps
with the simple iCoupler digital interfaces and stable performance
Bidirectional communication
characteristics. The need for external drivers and other discrete
3.3 V/5 V level translation
components is eliminated with these iCoupler products.
High temperature operation: 105C
Furthermore, iCoupler devices consume one-tenth to one-sixth
High data rate: dc to 90 Mbps (NRZ)
the power of optocouplers at comparable signal data rates.
Precise timing characteristics
2 ns maximum pulse width distortion
The ADuM3300/ADuM3301 isolators provide three independent
2 ns maximum channel-to-channel matching
isolation channels in a variety of channel configurations and
High common-mode transient immunity: >25 kV/s
data rates (see the Ordering Guide). All models operate with the
Output enable function
supply voltage on either side ranging from 3.3 V to 5.5 V, providing
16-lead SOIC wide body, RoHS-compliant package
compatibility with lower voltage systems as well as enabling a

voltage translation functionality across the isolation barrier. The
UL recognition: 2500 V rms for 1 minute per UL 1577
ADuM3300/ADuM3301 isolators have a patented refresh feature
CSA Component Acceptance Notice 5A
that ensures dc correctness in the absence of input logic

transitions and during power-up/power-down conditions.
DIN V VDE V 0884-10 (VDE V 0884-10): 2006-12
In comparison to ADuM1300/ADuM1301 isolators, ADuM3300/
VIORM = 560 V peak
ADuM3301 isolators contain various circuit and layout changes
CQC Certification per GB4943.1-2011
to provide increased capability relative to system-level IEC
APPLICATIONS 61000-4-x testing (ESD, burst, and surge). The precise capability
General-purpose multichannel isolation in these tests for either the ADuM1300/ADuM1301 or
SPI interface/data converter isolation ADuM3300/ADuM3301 products is strongly determined by the
RS-232/RS-422/RS-485 transceivers design and layout of the users system.
