Product details

Overview

ADUM142D0BRWZ-RL from Analog Devices is a quad-channel digital isolator using iCoupler® transformer-based isolation, delivering 3.75 kV_RMS withstand voltage in a wide-body SOIC-16 package. It supports 150 Mbps data rate, 15 ns max propagation delay at 1.8 V, and operates across 1.8 V to 5 V supply rails with level translation. It is used in isolated SPI interfaces for industrial PLCs and motor drives requiring high noise immunity.

For engineers reviewing the ADUM142D0BRWZ-RL datasheet, ADUM142D0BRWZ-RL pinout, ADUM142D0BRWZ-RL application, or ADUM142D0BRWZ-RL equivalent, key selection criteria include common-mode transient immunity (100 kV/µs), fail-safe output state configuration, AEC-Q100 qualification, and SOIC_W package creepage (7.8 mm) for reinforced insulation systems.

Technical Context

The ADUM142D0BRWZ-RL implements four independent unidirectional isolation channels using monolithic air-core transformers, enabling dc-correct signal transmission without input transitions. Its architecture ensures tight channel matching (≤3.0 ns codirectional skew) and low jitter (70 ps rms at 5 V).

It features dual supply domains (VDD1/VDD2), undervoltage lockout (1.5 V–1.6 V thresholds), and configurable fail-safe outputs-high or low-during input-side power loss. The device complies with DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation and supports 125°C operation.

ADUM142D0BRWZ-RL is housed in a 16-lead, RoHS-compliant, wide-body SOIC (SOIC_W, RW-16) package with 7.8 mm creepage and clearance, optimized for reinforced insulation in high-voltage systems.

Pin/Terminal	Circuit Role	Design Meaning
VDD1	Primary-side power supply	Supplies input-side logic and isolation transmitter; accepts 1.8 V–5 V.
GND1	Primary-side ground reference	Reference for all input signals and VDD1; must be separated from GND2 by isolation barrier.
INA, INB, INC, IND	Digital input channels	Unidirectional CMOS inputs accepting 1.8 V–5 V logic; no internal pull-ups unless enabled via DISABLE1.
VDD2	Secondary-side power supply	Supplies output-side logic and isolation receiver; independent voltage domain from VDD1.
GND2	Secondary-side ground reference	Reference for all output signals and VDD2; galvanically isolated from GND1.
OUTA, OUTB, OUTC, OUTD	Digital output channels	CMOS outputs referenced to VDD2; support 4 mA drive strength with fail-safe state control.
DISABLE1	Input disable control	Pull-down input that disables all inputs when driven high; enables tristate behavior on outputs if configured.
VE2	Output enable control	Pull-up input that enables/disables output drivers; low = outputs disabled (high-Z), high = active.

Key Features

Feature	Design Value
iCoupler® transformer isolation	Eliminates LED aging and CTR degradation of optocouplers; guarantees >50-year insulation lifetime at rated stress.
1.8 V to 5 V dual-supply operation	Enables direct interfacing between ultra-low-voltage controllers (e.g., ARM Cortex-M0+) and higher-voltage peripherals without external level shifters.
100 kV/µs common-mode transient immunity	Prevents data corruption during fast transients from IGBT switching or lightning surges in industrial inverters.
Fail-safe output configuration	Ensures deterministic output state (high or low) during primary-side power failure-critical for functional safety in ISO 13849 systems.
AEC-Q100 Grade 1 qualification	Validated for automotive use including engine control units and battery management systems operating up to 125°C ambient.
SOIC_W package with 7.8 mm creepage	Meets reinforced insulation requirements for 600 V_RMS working voltage per IEC 60664-1, eliminating need for slotting or spacing on PCB.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADUM142E0BRWZ-RL	Pin-compatible variant with different fail-safe output state (low vs. high); identical SOIC_W package and 3.75 kV_RMS rating.	Used where default output must be logic low during power loss (e.g., disable-on-fault safety interlocks).	Select ADUM142E0BRWZ-RL only when system-level fail-safe logic requires active-low assertion on isolation barrier loss.
SI8642ED-B-IS	Capacitive isolation; 5 kV_RMS rating; 150 Mbps; SOIC_W package; no AEC-Q100 qualification.	Targeted at industrial automation, not automotive; lacks automotive temperature validation and functional safety documentation.	Choose SI8642ED-B-IS for cost-sensitive non-automotive designs where AEC-Q100 is not mandated and higher isolation voltage is beneficial.

Compared with ADUM142E0BRWZ-RL, the ADUM142D0BRWZ-RL provides complementary fail-safe polarity for safety-critical reset paths, while SI8642ED-B-IS offers higher isolation voltage but lacks automotive qualification and has different EMC performance due to capacitive coupling architecture.

FAQ

What is the maximum guaranteed data rate for ADUM142D0BRWZ-RL?

The ADUM142D0BRWZ-RL guarantees a data rate of 150 Mbps across all four channels under specified operating conditions (CL = 15 pF, CMOS levels). This is validated over temperature (−40°C to +125°C) and supply ranges (1.8 V–5 V), making it suitable for high-speed SPI and digital encoder interfaces. Higher rates may function but are not production-guaranteed.

Does ADUM142D0BRWZ-RL support level translation between different supply voltages?

Yes, ADUM142D0BRWZ-RL supports true 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 allows seamless interfacing-for example-between a 1.8 V FPGA I/O bank and a 3.3 V isolated ADC, without external level-shifting circuitry.

What safety certifications does ADUM142D0BRWZ-RL hold?

ADUM142D0BRWZ-RL is certified to UL 1577 (3750 V_RMS/1 min), DIN EN IEC 60747-17 (VDE 0884-17), IEC/EN/CSA 60950-1, IEC/CSA 60601-1, IEC/CSA 61010-1, and CQC GB 4943.1. Its 7.8 mm creepage/clearance in the RW-16 package satisfies reinforced insulation requirements for 600 V_RMS working voltage.

How does the fail-safe output function work on ADUM142D0BRWZ-RL?

The ADUM142D0BRWZ-RL features a user-selectable fail-safe output state (high or low) activated when the input-side supply (VDD1) is absent or the DISABLE1 pin is asserted. For the D0 variant, outputs default to logic high-ensuring active-enable states persist during upstream power loss, critical for safety interlocks in motor control systems.

Is ADUM142D0BRWZ-RL pin-compatible with earlier ADuM140x/ADuM141x families?

No, ADUM142D0BRWZ-RL is not pin-compatible with ADuM1400/ADuM1401/ADuM1402. However, the ADuM142E1/ADuM142D1 variants are pin-compatible with ADuM1400/ADuM1401/ADuM1402. The ADUM142D0BRWZ-RL uses a distinct pinout optimized for its specific enable/disable control architecture and fail-safe configuration.
