Product details

Overview

ADUM242D0BRIZ from Analog Devices is a quad-channel digital isolator based on iCoupler® technology, providing 5.0 kV_rms reinforced insulation, 150 Mbps guaranteed data rate, and 13 ns max propagation delay at 5 V operation. It supports 1.8 V to 5 V level translation across the isolation barrier and is qualified for automotive applications in a 16-lead SOIC_W package.

For engineers reviewing the ADUM242D0BRIZ datasheet, ADUM242D0BRIZ pinout, ADUM242D0BRIZ application, or ADUM242D0BRIZ equivalent, key selection criteria include reinforced insulation rating (VIORM = 849 V_peak), fail-safe high/low output options, common-mode transient immunity (100 kV/µs), and compatibility with SPI/data converter isolation in industrial and medical systems.

Technical Context

The ADUM242D0BRIZ implements monolithic air-core transformer-based isolation with independent bidirectional channels, ensuring dc-correct output states even without input transitions. Its architecture delivers tight channel matching (≤3.0 ns) and low pulse width distortion (≤3 ns), critical for timing-sensitive serial interfaces.

It features dual supply domains (VDD1/VDD2), undervoltage lockout (1.5 V–1.6 V thresholds), and two enable/disable control schemes-VE2 pull-up and DISABLE1 pull-down-supporting flexible system-level power sequencing and fault management in isolated communication paths.

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
ADUM242E0BRIZ	Pin-compatible; E0 variant offers fail-safe low output (vs. D0's fail-high); identical timing and insulation specs.	Required where default-low output state is mandated for safety interlocks or reset circuits.	Select ADUM242E0BRIZ when system-level fault response requires active-low default behavior.
SI8642ED-B-IS	4-channel, 5 kV_rms isolator; 150 Mbps rated; 13 ns propagation delay; different pinout and enable logic (active-low EN).	Compatible in SPI isolation but requires PCB layout revision due to non-pin-compatible pin assignment.	Choose SI8642ED-B-IS only if redesigning layout and requiring Silicon Labs' specific safety certification path (UL 1577, VDE 0884-11).

Compared with ADUM242E0BRIZ and SI8642ED-B-IS, ADUM242D0BRIZ provides fail-safe high output without layout change, maintains identical timing performance and automotive qualification, and avoids revalidation of isolation barrier layout due to SOIC_W pinout continuity within the ADuM242x family.

FAQ

What is the maximum guaranteed data rate for ADUM242D0BRIZ?

The ADUM242D0BRIZ guarantees a maximum data rate of 150 Mbps across its full operating temperature range (−40°C to +125°C) and supply voltage range (1.8 V to 5 V). This rating is verified per the datasheet's switching specifications tables and applies to all four channels simultaneously under standard test conditions (CL = 15 pF, CMOS levels). Higher rates may be achievable but are not production-guaranteed.

Does ADUM242D0BRIZ support level translation between different supply voltages?

Yes, ADUM242D0BRIZ supports bidirectional level translation: VDD1 (input side) and VDD2 (output side) operate independently from 1.8 V to 5 V. For example, it can translate 1.8 V logic from an MCU on VDD1 to 3.3 V logic for an ADC on VDD2. Input threshold voltages scale with respective supply (VIH = 0.7 × VDDx), and output drive strength adapts accordingly-ensuring robust interfacing without external level shifters.

What safety certifications does ADUM242D0BRIZ hold?

ADUM242D0BRIZ holds UL 1577 (5000 V_rms for 1 min), DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation (849 V_peak), IEC/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 61010-1. These certifications are validated for the RW-16 SOIC_W package and confirm compliance for medical, industrial, and test equipment applications requiring reinforced isolation.

How does the fail-safe behavior of ADUM242D0BRIZ work?

ADUM242D0BRIZ (D0 variant) defaults to a high-output state on all four channels (OA–OD) when VDD1 is unpowered or DISABLE1 is asserted high. This behavior is implemented via internal circuitry that overrides normal signal transmission during fault conditions. It ensures predictable logic states in safety-critical systems-such as disabling a motor driver or asserting a hardware reset-without requiring external pull-up resistors or supervision logic.

Is ADUM242D0BRIZ pin-compatible with earlier ADuM240x/ADuM241x devices?

No-ADUM242D0BRIZ is not pin-compatible with ADuM2400/ADuM2401/ADuM2402. However, the ADuM242E1/ADuM242D1 variants are explicitly stated as pin-compatible with those legacy parts. The D0/E0 variants (including ADUM242D0BRIZ) share the same SOIC_W footprint and pinout as other ADuM242x devices but differ in fail-safe configuration and enable logic mapping versus the ADuM240x/241x families.
