Quad-Channel, Digital Isolators, Enhanced System-Level ESD Reliability Data Sheet ADuM3400/ADuM3401/ADuM3402 FEATURES GENERAL DESCRIPTION 1 Enhanced system-level ESD performance per IEC 61000-4-x The ADuM3400/ADuM3401/ADuM3402 are 4-channel digital Low power operation isolators based on the Analog Devices, Inc., iCoupler technol- 5 V operation ogy. Combining high speed CMOS and monolithic air core 1.4 mA per channel maximum at 0 Mbps to 2 Mbps transformer technology, these isolation components provide 4.3 mA per channel maximum at 10 Mbps outstanding performance characteristics superior to alternatives 34 mA per channel maximum at 90 Mbps such as optocoupler devices. 3.3 V operation iCoupler devices remove the design difficulties commonly 0.9 mA per channel maximum at 0 Mbps to 2 Mbps associated with optocouplers. Typical optocoupler concerns 2.4 mA per channel maximum at 10 Mbps regarding uncertain current transfer ratios, nonlinear transfer 20 mA per channel maximum at 90 Mbps functions, and temperature and lifetime effects are eliminated Bidirectional communication with the simple iCoupler digital interfaces and stable performance 3.3 V/5 V level translation characteristics. The need for external drivers and other discrete High temperature operation: 105C components is eliminated with these iCoupler products. Further- High data rate: dc to 90 Mbps (NRZ) more, iCoupler devices consume one-tenth to one-sixth the Precise timing characteristics power of optocouplers at comparable signal data rates. 2 ns maximum pulse width distortion The isolators provide four independent isolation channels in a 2 ns maximum channel-to-channel matching variety of channel configurations and data rates (see the Ordering High common-mode transient immunity: >25 kV/s Guide). All models operate with the supply voltage on either Output enable function side ranging from 3.0 V to 5.5 V, providing compatibility with 16-lead SOIC wide body, RoHS-compliant package lower voltage systems as well as enabling a voltage translation Safety and regulatory approvals functionality across the isolation barrier. The isolators have a UL recognition: 2500 V rms for 1 minute per UL 1577 patented refresh feature that ensures dc correctness in the absence CSA Component Acceptance Notice 5A of input logic transitions and during power-up/power-down VDE Certificate of Conformity conditions. DIN V VDE V 0884-10 (VDE V 0884-10): 2006-12 V = 560 V peak IORM In comparison to the ADuM1400/ADuM1401/ADuM1402 isolators, the ADuM3400/ADuM3401/ADuM3402 isolators APPLICATIONS contain various circuit and layout changes to provide increased General-purpose multichannel isolation capability relative to system-level IEC 61000-4-x testing (ESD/ SPI/data converter isolation burst/surge). The precise capability in these tests for either set of RS-232/RS-422/RS-485 transceivers isolators is strongly determined by the design and layout of the Industrial field bus isolation user board or module.
