Product details
Overview
ADUM2402CRWZ from Analog Devices is a quad-channel digital isolator using iCoupler® transformer-based isolation technology, configured with two bidirectional channels (A/B) and two unidirectional channels (C/D), operating at up to 90 Mbps with <2 ns pulse width distortion and <5 ns channel-to-channel matching. It supports 2.7 V to 5.5 V supply on either side, enabling 3 V/5 V level translation in industrial motor drives and medical power supplies.
For engineers reviewing the ADUM2402CRWZ datasheet, ADUM2402CRWZ pinout, ADUM2402CRWZ application, or ADUM2402CRWZ equivalent, this page delivers verified timing specs, isolation barrier performance, SOIC-W package layout, and real-world substitution guidance for high-reliability system design.
Technical Context
The ADUM2402CRWZ implements monolithic air-core transformer coupling per channel, eliminating LED-photodiode aging and CTR drift inherent in optocouplers. Its architecture includes integrated refresh circuitry ensuring DC correctness during idle periods and power transitions.
It features independent VDD1/VDD2 domains supporting asymmetric operation (e.g., 5 V primary / 3 V secondary), output enable control per side, and guaranteed propagation delay skew ≤14 ns under mixed-voltage conditions - critical for synchronized gate driving and isolated feedback loops.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8642ED-B-IS | Capacitive isolation; 100 Mbps max; 2.5 kV rms rating; different pinout (SOIC-16 but non-compatible) | Lower isolation voltage limits use in non-medical consumer-grade inverters only | Select when cost sensitivity outweighs regulatory certification needs and board layout permits rework |
| ISO6742QDWR | Capacitive isolation; 50 Mbps max; 5000 V rms; 16-pin SOIC-W but pinout differs in OE placement and channel assignment | Limited data rate restricts use in high-resolution encoder or fast SPI interfaces | Prefer for TI ecosystem designs where ADS131M04 ADCs require companion isolators with shared enable logic |
Compared with SI8642ED-B-IS and ISO6742QDWR, ADUM2402CRWZ delivers superior timing precision (<2 ns PWD), higher certified isolation (5000 V rms), and true bidirectional channel capability - making it optimal for safety-critical, high-speed industrial and medical systems where deterministic latency and regulatory compliance are mandatory.

FAQ
What is the maximum guaranteed data rate for ADUM2402CRWZ?
The ADUM2402CRWZ is specified for a maximum data rate of 90 Mbps under NRZ conditions with guaranteed pulse width distortion ≤2 ns. While the datasheet notes a typical capability up to 120 Mbps, system-level validation at 90 Mbps ensures full timing margin compliance across temperature and voltage extremes.
Does ADUM2402CRWZ support bidirectional communication on all four channels?
No - ADUM2402CRWZ has two bidirectional channels (A and B) and two unidirectional channels (C and D). This configuration matches common interface needs such as I²C (bidirectional) plus fault/status reporting (unidirectional), unlike ADUM2400 (all unidirectional) or ADUM2401 (three unidirectional, one bidirectional).
What safety certifications apply to ADUM2402CRWZ?
ADUM2402CRWZ holds UL 1577 (5000 V rms, 1 minute), IEC/EN/CSA 62368-1, IEC/CSA 60601-1 (medical), IEC/CSA 61010-1 (test equipment), CQC GB 4943.1, and DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 645 V peak - covering reinforced insulation requirements for industrial and Class II medical applications.
Can ADUM2402CRWZ operate with different supply voltages on each side?
Yes - ADUM2402CRWZ supports mixed-voltage operation: VDD1 and VDD2 may independently range from 2.7 V to 5.5 V. For example, it can translate 3.3 V logic on VDD1 to 5 V outputs on VDD2, eliminating external level shifters in heterogeneous voltage systems.
How does the refresh feature in ADUM2402CRWZ improve reliability?
The patented refresh circuitry in ADUM2402CRWZ continuously monitors static input states and injects periodic pulses to maintain correct output logic levels during prolonged DC conditions or power transitions - preventing output latch-up and ensuring fail-safe behavior in safety-critical motor control and medical monitoring systems.
