Product details
Overview
ADUM242D0BRWZ-RL from Analog Devices is a quad-channel, 5.0 kVrms digital isolator using iCoupler® transformer-based technology, designed for high-noise industrial and medical systems. It delivers 150 Mbps guaranteed data rate, 13 ns max propagation delay at 5 V, and operates across 1.8 V–5 V supply rails with fail-safe high output configuration. It is used in isolated SPI interfaces for motor drives and PLC I/O modules.
For engineers reviewing the ADUM242D0BRWZ-RL datasheet, ADUM242D0BRWZ-RL pinout, ADUM242D0BRWZ-RL application, or ADUM242D0BRWZ-RL equivalent, key selection criteria include reinforced insulation rating (849 Vpeak), common-mode transient immunity (100 kV/µs), channel matching (≤3.0 ns), and SOIC_W package creepage (7.8 mm) for IEC 60601-1 compliance.
Technical Context
The ADUM242D0BRWZ-RL implements four independent unidirectional isolation channels with fixed input-to-output directionality (VDD1 side inputs, VDD2 side outputs). Its iCoupler® architecture replaces optocouplers with monolithic air-core transformers, ensuring dc-correct output states without input transitions and eliminating LED aging or temperature drift.
It features two enable inputs (VE1, VE2) supporting tristate output control per side, undervoltage lockout (1.5 V–1.6 V thresholds), and failsafe-high output behavior when input power is absent. The device supports level translation between 1.8 V and 5 V logic domains on either side of the isolation barrier.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad digital isolator applications.

FAQ
What is the fail-safe output behavior of the ADUM242D0BRWZ-RL?
The ADUM242D0BRWZ-RL defaults to a high output state when the input-side power supply (VDD1) is absent or the VE1 enable pin is asserted low. This fail-safe high behavior ensures motor enable lines or safety interlocks remain de-energized during fault conditions, directly supporting SIL-2 and IEC 61508 functional safety architectures. The ADUM242D0BRWZ-RL maintains this state regardless of input signal activity or output-side supply status.
Does the ADUM242D0BRWZ-RL support bidirectional data flow?
No, the ADUM242D0BRWZ-RL implements four unidirectional channels - all inputs reside on the VDD1 side (pins 1–4), and all outputs reside on the VDD2 side (pins 9–12). For bidirectional protocols like I²C, a separate isolator pair or a different part number (e.g., ADUM240D0BRWZ-RL with configurable direction) is required. The ADUM242D0BRWZ-RL is optimized for SPI, parallel bus, and digital control signal isolation where direction is fixed.
What safety certifications apply to the ADUM242D0BRWZ-RL?
The ADUM242D0BRWZ-RL carries UL 1577 (5000 Vrms), DIN EN IEC 60747-17 (VDE 0884-17), IEC/CSA 62368-1, IEC/CSA 60601-1 (2-MOPP), and IEC/CSA 61010-1 approvals. Its reinforced insulation rating of 849 Vpeak and 7.8 mm creepage meet stringent medical and industrial safety requirements. Certification documentation for the ADUM242D0BRWZ-RL is available through Analog Devices' official safety portal.
Can the ADUM242D0BRWZ-RL operate with mismatched supply voltages?
Yes - the ADUM242D0BRWZ-RL supports independent 1.8 V–5 V supplies on VDD1 and VDD2 sides, enabling level translation. For example, it can interface a 1.8 V FPGA (VDD1) with a 5 V DAC (VDD2) while maintaining signal integrity and timing specifications. Input thresholds scale with VDD1 (VIH = 0.7×VDD1), and output drive levels conform to VDD2 (VOH = VDD2 − 0.1 V), making the ADUM242D0BRWZ-RL ideal for heterogeneous voltage domain bridging.
How does the ADUM242D0BRWZ-RL compare to optocouplers in terms of reliability?
The ADUM242D0BRWZ-RL uses iCoupler® monolithic transformer technology, eliminating LED wear-out mechanisms that limit optocoupler lifetime to ~10 years. Accelerated life testing shows >50-year insulation lifetime per IEC 60747-17, with no performance degradation over temperature or time. Unlike optocouplers, the ADUM242D0BRWZ-RL guarantees consistent propagation delay, CMTI, and channel matching across its full operating range - critical for deterministic real-time systems.
