Product details
Overview
ADUM142E1WBRWZ-RL from Analog Devices is a quad-channel digital isolator based on iCoupler® transformer technology, providing 3.75 kVRMS reinforced isolation in a wide-body SOIC-16 package. It delivers 150 Mbps guaranteed data rate, 15 ns max propagation delay at 1.8 V operation, and high common-mode transient immunity of 100 kV/µs - enabling robust SPI, RS-485, and industrial field bus isolation in motor drives and PLC I/O modules.
For engineers reviewing the ADUM142E1WBRWZ-RL datasheet, ADUM142E1WBRWZ-RL pinout, ADUM142E1WBRWZ-RL application, or ADUM142E1WBRWZ-RL equivalent, this page provides verified specifications, fail-safe output behavior, AEC-Q100 qualification status, voltage translation (1.8 V to 5 V), and regulatory compliance including UL 1577, VDE 0884-17, and IEC 60601-1.
Technical Context
The ADUM142E1WBRWZ-RL implements four independent unidirectional isolated channels using monolithic air-core transformers, with dc-correct output logic states maintained even during input inactivity. Its architecture supports fail-safe high or low output options and includes integrated undervoltage lockout (UVLO) with 1.6 V threshold on both sides.
It operates across dual supply ranges (1.7–1.9 V, 2.25–2.75 V, 3.0–3.6 V, 4.5–5.5 V), enabling level translation between mismatched logic domains. Channel matching is ≤3.0 ns codirectional and ≤3.0 ns opposing-direction, with pulse width distortion ≤3 ns and jitter as low as 70 psrms at 5 V.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM142D1WBRWZ-RL | Same RW-16 package and 3.75 kVRMS rating, but with default fail-safe low (vs. high) output state | Preferred where system defaults to logic low on fault - e.g., de-energizing safety relays | Select when fail-safe behavior must assert low instead of high during power loss or disable |
| SI8642ED-B-IS | Capacitive isolation; 5 kVRMS rating; 150 Mbps; different pinout (SOIC-16 but non-pin-compatible) | Requires PCB layout change; supports higher ambient temperature (125°C) but lacks AEC-Q100 certification | Consider only if redesign is acceptable and medical certification is not required |

FAQ
What is the isolation voltage rating of the ADUM142E1WBRWZ-RL?
The ADUM142E1WBRWZ-RL has a rated dielectric insulation voltage of 3.75 kVRMS for 1 minute, certified per UL 1577 and VDE 0884-17 (DIN EN IEC 60747-17). This corresponds to the RW-16 wide-body SOIC package variant, which provides 7.8 mm creepage and clearance distances for reinforced insulation in high-voltage systems.
Does the ADUM142E1WBRWZ-RL support level translation between different supply voltages?
Yes, the ADUM142E1WBRWZ-RL supports independent 1.7 V to 5.5 V supplies on each side, enabling seamless level translation - for example, interfacing a 1.8 V microcontroller (VDD1) with a 3.3 V ADC or 5 V PLC backplane (VDD2) without external level shifters.
What fail-safe behavior does the ADUM142E1WBRWZ-RL exhibit on power loss?
The ADUM142E1WBRWZ-RL is an "E1" variant, meaning its outputs transition to a pre-determined high state when the input-side power supply is removed or the DISABLE1 pin is asserted. This fail-safe high behavior ensures defined logic levels in safety-critical control paths.
Is the ADUM142E1WBRWZ-RL pin-compatible with earlier ADuM140x series isolators?
Yes, the ADUM142E1WBRWZ-RL is pin-compatible with ADuM1400/ADuM1401/ADuM1402 in the same RW-16 package. This backward compatibility allows drop-in replacement in existing designs without PCB layout changes or firmware modifications.
What safety certifications apply to the ADUM142E1WBRWZ-RL?
The ADUM142E1WBRWZ-RL is certified to UL 1577 (3000 V rms), VDE 0884-17 (VIORM = 565 V peak), IEC/EN/CSA 60950-1, IEC/CSA 60601-1 (medical), and IEC/CSA 61010-1 (test equipment), making it suitable for Class I and Class II medical devices and industrial safety systems.
