Part Details:

Quad-Channel, Digital Isolators, Enhanced System-Level ESD Reliability ADuM3400/ADuM3401/ADuM3402 FEATURES GENERAL DESCRIPTION Enhanced system-level ESD performance per IEC 61000-4-x The ADuM340x1 are 4-channel digital isolators based on the Low power operation Analog Devices, Inc. iCoupler® technology. Combining high 5 V operation speed CMOS and monolithic air core transformer technology, 1.4 mA per channel maximum @ 0 Mbps to 2 Mbps these isolation components provide outstanding performance 4.3 mA per channel maximum @ 10 Mbps characteristics superior to alternatives such as optocoupler devices. 34 mA per channel maximum @ 90 Mbps 3 V operation iCoupler devices remove the design difficulties commonly 0.9 mA per channel maximum @ 0 Mbps to 2 Mbps associated with optocouplers. Typical optocoupler concerns 2.4 mA per channel maximum @ 10 Mbps regarding uncertain current transfer ratios, nonlinear transfer 20 mA per channel maximum @ 90 Mbps functions, and temperature and lifetime effects are eliminated Bidirectional communication with the simple iCoupler digital interfaces and stable performance 3 V/5 V level translation characteristics. The need for external drivers and other discrete High temperature operation: 105°C 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 power Precise timing characteristics of optocouplers at comparable signal data rates. 2 ns maximum pulse width distortion The ADuM340x isolators provide four independent isolation 2 ns maximum channel-to-channel matching channels in a variety of channel configurations and data rates High common-mode transient immunity: >25 kV/s (see the Ordering Guide). All models operate with the supply Output enable function voltage on either side ranging from 2.7 V to 5.5 V, providing 16-lead SOIC wide body, RoHS-compliant package compatibility with lower voltage systems as well as enabling a Safety and regulatory approvals voltage translation functionality across the isolation barrier. The UL recognition: 2500 V rms for 1 minute per UL 1577 ADuM340x isolators have a patented refresh feature that ensures dc CSA Component Acceptance Notice #5A correctness in the absence of input logic transitions and during VDE Certificate of Conformity power-up/power-down conditions. DIN V VDE V 0884-10 (VDE V 0884-10): 2006-12 VIORM = 560 V peak
