Product details

Overview

ADUM142E1WBRWZ from Analog Devices is a quad-channel digital isolator based on iCoupler® technology, providing 3.75 kV_RMS 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 supports 1.8 V to 5 V level translation across the isolation barrier-enabling robust SPI and data converter isolation in industrial motor drives.

For engineers reviewing the ADUM142E1WBRWZ datasheet, ADUM142E1WBRWZ pinout, ADUM142E1WBRWZ application, or ADUM142E1WBRWZ equivalent, key selection criteria include its 3.75 kV_RMS isolation rating, AEC-Q100 qualification for automotive use, fail-safe high/low output options, and compatibility with low-voltage microcontrollers and isolated ADCs/DACs.

Technical Context

The ADUM142E1WBRWZ implements four independent unidirectional CMOS-isolated channels using monolithic air-core transformers, ensuring dc-correct output states without input transitions. Its architecture enables tight channel matching (≤3.0 ns codirectional skew) and ultra-low jitter (70 ps rms at 5 V), critical for timing-sensitive serial interfaces.

It features dual supply domains (VDD1/VDD2), undervoltage lockout (1.5 V–1.6 V thresholds), and configurable enable/disable inputs-supporting flexible power sequencing and fail-safe behavior during supply loss. The device meets DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation and operates up to +125°C ambient.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADUM142E0WBRWZ	Different fail-safe default state (low vs. high); otherwise identical pinout, specs, and package.	Used where output must default to logic low on power loss (e.g., disable-enable logic in safety interlocks).	Select ADUM142E0WBRWZ only when fail-safe low behavior is required; ADUM142E1WBRWZ defaults high.
SI8642ED-B-IS	Capacitive isolation; 5 kV_RMS rating; 150 Mbps; but no AEC-Q100 qualification and higher typical propagation delay (18 ns).	Suitable for industrial automation but not automotive or medical applications requiring AEC-Q100 or IEC 60601-1 certification.	Choose SI8642ED-B-IS for cost-sensitive non-automotive designs where 5 kV_RMS and capacitive architecture are preferred.

Compared with ADUM142E0WBRWZ, the ADUM142E1WBRWZ provides identical performance and layout compatibility but ensures fail-safe high output-critical for enabling circuits that require active-high default signaling. Against SI8642ED-B-IS, it offers superior automotive qualification, lower propagation delay, and transformer-based reliability over lifetime.

FAQ

What is the isolation voltage rating of the ADUM142E1WBRWZ?

The ADUM142E1WBRWZ has a rated dielectric insulation voltage of 3.75 kV_RMS for 1 minute, verified per UL 1577 and DIN EN IEC 60747-17 (VDE 0884-17). This corresponds to the RW-16 wide-body SOIC package configuration and supports reinforced insulation in medical and industrial safety standards including IEC 60601-1 and IEC 61010-1.

Does the ADUM142E1WBRWZ support 1.8 V logic levels on both sides?

Yes, the ADUM142E1WBRWZ supports independent 1.8 V to 5 V operation on both VDD1 and VDD2 supplies. At 1.8 V, it guarantees 15 ns maximum propagation delay and 150 Mbps data rate, enabling direct interfacing with ultra-low-power microcontrollers and sensors without external level translation circuitry.

How does the fail-safe feature work on the ADUM142E1WBRWZ?

The ADUM142E1WBRWZ defaults to a logic high output state when the input power supply is absent or the DISABLE1 pin is asserted. This behavior is fixed per the "E1" suffix and eliminates undefined outputs during power sequencing or fault conditions-ensuring predictable control of downstream drivers or safety relays in the ADUM142E1WBRWZ-based system.

Is the ADUM142E1WBRWZ pin-compatible with earlier ADuM140x/ADuM141x devices?

Yes, the ADUM142E1WBRWZ is pin-compatible with ADuM1400/ADuM1401/ADuM1402 and backward compatible with ADuM140E1/ADuM141E1. This allows drop-in replacement in existing layouts while delivering improved common-mode transient immunity (100 kV/µs) and tighter channel matching (≤3.0 ns) compared to legacy variants.

What safety certifications apply to the ADUM142E1WBRWZ?

The ADUM142E1WBRWZ is certified to UL 1577 (3000 V rms), IEC/EN/CSA 60950-1, IEC/CSA 60601-1, IEC/CSA 61010-1, CQC GB 4943.1, and DIN EN IEC 60747-17 (VDE 0884-17). It also meets AEC-Q100 Grade 1 for automotive applications, confirming reliability from −40°C to +125°C ambient.
