Product details

Overview

ADUM242D1BRWZ-RL from Analog Devices is a quad-channel, 5.0 kV_rms digital isolator using iCoupler® technology, designed for high-noise industrial and medical systems requiring galvanic signal separation between microcontrollers and isolated peripherals. It delivers 150 Mbps guaranteed data rate, 13 ns max propagation delay at 5 V, and operates across 1.8 V to 5 V supply rails on both sides with fail-safe high output configuration.

For engineers reviewing the ADUM242D1BRWZ-RL datasheet, ADUM242D1BRWZ-RL pinout, ADUM242D1BRWZ-RL application, or ADUM242D1BRWZ-RL equivalent, this page provides verified specifications, SOIC_W package layout, safety-certified isolation parameters, and real-world use cases in SPI isolation and motor control gate driver interfaces.

Technical Context

The ADUM242D1BRWZ-RL implements four independent unidirectional channels using monolithic air-core transformers, enabling dc-correct operation without input transitions. Its architecture supports asymmetric voltage translation (e.g., 1.8 V logic side to 5 V system side) and includes integrated undervoltage lockout (UVLO) with 1.6 V threshold on both VDD1 and VDD2 rails.

It features tight channel matching (≤3.0 ns codirectional skew), low jitter (70 ps rms at 5 V), and robust common-mode transient immunity of 100 kV/µs - validated under 1000 V common-mode step with 800 V magnitude per IEC 60747-17 test conditions.

Key Specifications

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
ADUM242E1BRWZ-RL	Pin-compatible but with fail-safe low output state instead of high; identical timing, isolation, and supply specs.	Preferred where default-low output is required for active-high enable logic or failsafe gate driver shutdown.	Select ADUM242E1BRWZ-RL only when system-level fault behavior mandates low-state default on power loss.
SI8642ED-B-IS	Capacitive isolation; 5 kV_rms, 150 Mbps, but higher typical propagation delay (18 ns) and lower CMTI (75 kV/µs).	Acceptable for non-critical industrial controls but not recommended for high-dV/dt motor drives or medical 2-MOPP designs.	Choose SI8642ED-B-IS only if cost sensitivity outweighs need for lowest jitter and highest CMTI in safety-critical loops.

Compared with ADUM242E1BRWZ-RL, the ADUM242D1BRWZ-RL provides fail-safe high output essential for keeping gate drivers disabled during fault; versus SI8642ED-B-IS, it delivers superior noise immunity and tighter timing for closed-loop motion control.

FAQ

What is the maximum guaranteed data rate for ADUM242D1BRWZ-RL?

The ADUM242D1BRWZ-RL 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 specification is validated per the datasheet's switching characteristics tables and applies to all four channels simultaneously under CL = 15 pF load conditions.

Does ADUM242D1BRWZ-RL support level translation between different supply voltages?

Yes, ADUM242D1BRWZ-RL supports bidirectional level translation: VDD1 can operate from 1.8 V to 5 V independently of VDD2, which also ranges from 1.8 V to 5 V. This enables direct interfacing between low-voltage microcontrollers (e.g., 1.8 V ARM Cortex-M) and 3.3 V or 5 V peripheral ICs without external level shifters.

What safety certifications apply to ADUM242D1BRWZ-RL?

ADUM242D1BRWZ-RL holds UL 1577 (5000 V_rms), DIN EN IEC 60747-17 (VDE 0884-17), IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 62368-1 certifications. Its RW-16 SOIC_W package provides reinforced insulation with 7.8 mm creepage and clearance, meeting requirements for medical and industrial safety-critical systems.

How does the fail-safe output behavior work on ADUM242D1BRWZ-RL?

The ADUM242D1BRWZ-RL features a fail-safe high output configuration: when either VDD1 or VDD2 drops below UVLO threshold (1.5 V), all four outputs transition to and hold a logic high state. This ensures gate drivers remain off and control signals default to safe states during power-up, brownout, or supply sequencing faults.

What is the common-mode transient immunity (CMTI) specification for ADUM242D1BRWZ-RL?

ADUM242D1BRWZ-RL achieves a minimum common-mode transient immunity of 75 kV/µs and a typical value of 100 kV/µs, measured per IEC 60747-17 with 1000 V common-mode step and 800 V transient magnitude. This performance ensures reliable operation in high-dV/dt environments such as motor drives with SiC/GaN inverters.
