Product details
Overview
ADUM142D0BRZ-RL7 from Analog Devices is a quad-channel digital isolator based on iCoupler® technology, providing 3.0 kVRMS galvanic isolation between input and output sides. It supports 150 Mbps data rate, 13 ns max propagation delay at 5 V, and operates across 1.8 V to 5 V supply rails with level translation capability. It is used in SPI isolation for industrial PLCs where high noise immunity and fail-safe operation are required.
For engineers reviewing the ADUM142D0BRZ-RL7 datasheet, ADUM142D0BRZ-RL7 pinout, ADUM142D0BRZ-RL7 application, or ADUM142D0BRZ-RL7 equivalent, key selection criteria include common-mode transient immunity (100 kV/µs), AEC-Q100 qualification, SOIC-16 narrow-body package, and configurable fail-safe output state (high/low) during input power loss.
Technical Context
The ADUM142D0BRZ-RL7 implements four independent unidirectional isolation channels using monolithic air-core transformers, ensuring dc-correct output even without input transitions. Its architecture eliminates optocoupler aging and timing drift while enabling tight channel matching (≤3.0 ns codirectional skew).
It features dual supply domains (VDD1/VDD2), undervoltage lockout (1.6 V threshold), and two enable/disable control options (VE2 pull-up, DISABLE1 pull-down). Fail-safe behavior is factory-configured - D0 suffix denotes default-low outputs when input side is unpowered.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 3.0 kVRMS for 1 minute - meets UL 1577, IEC/EN/CSA 60950-1, and IEC 60601-1 safety standards |
| Max Data Rate | 150 Mbps - guaranteed minimum throughput for high-speed serial interfaces like SPI and RS-485 transceivers |
| Propagation Delay | 13 ns max at 5 V - enables sub-10 ns timing margins in real-time control loops |
| Common-Mode Transient Immunity | 100 kV/µs - sustains reliable operation in motor drive and power converter environments with fast dv/dt noise |
| Supply Voltage Range | 1.8 V to 5 V per side - supports mixed-voltage system interfacing (e.g., 1.8 V FPGA to 3.3 V ADC) |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial ambient conditions |
| Fail-Safe Output State | Low (D0 variant) - outputs default to logic low when VDD1 is absent or DISABLE1 asserted |
Pinout & Package
ADUM142D0BRZ-RL7 is housed in a 16-lead, RoHS-compliant, narrow-body SOIC (R-16) package with 4.0 mm creepage/clearance and 3.0 kVRMS isolation rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Input Channels A–D | Logic-level inputs referenced to VDD1; accept 1.8 V–5 V CMOS signals |
| 5, 6 | VDD1, GND1 | Primary-side power and ground for input domain and internal transmitter circuitry |
| 7, 8, 15, 16 | Output Channels A–D | Isolated logic outputs referenced to VDD2; support 1.8 V–5 V levels with fail-safe low default |
| 9, 10 | VDD2, GND2 | Secondary-side power and ground for output domain and receiver circuitry |
| 11 | DISABLE1 | Active-high input that forces all outputs into high-impedance state when driven high |
| 14 | VE2 | Enable input with internal pull-up; must be tied low to activate output drivers |
Key Features
| Feature | Design Value |
|---|---|
| iCoupler® transformer isolation | Replaces optocouplers with no LED degradation, >50-year lifetime, and <3 ns channel-to-channel skew |
| Level translation | Enables bidirectional voltage translation between 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains across isolation barrier |
| AEC-Q100 qualification | Qualified to Grade 1 (−40°C to +125°C) for automotive powertrain and body electronics applications |
| Dual enable control | Independent DISABLE1 (input-side tristate) and VE2 (output-side enable) allow flexible power sequencing and fault recovery |
| Robust noise immunity | 100 kV/µs CMTI ensures reliable operation in high-noise industrial motor drives and inverters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM142E0BRZ-RL7 | Pin-compatible but configured for fail-safe high output (E0) instead of low (D0); identical timing, power, and isolation specs | Required where system logic defaults to active-high enable or reset states during power loss | Select ADUM142E0BRZ-RL7 only if hardware design requires high-default outputs; otherwise ADUM142D0BRZ-RL7 maintains compatibility with existing D0-based layouts |
| SI8640ED-B-IS | Capacitive isolation; 5 kVRMS rating; 150 Mbps; 18 ns max propagation delay; different pinout and enable logic (active-low EN) | Used in cost-sensitive consumer-grade designs where higher isolation voltage offsets slightly higher propagation delay | Not pin-compatible; requires PCB redesign and firmware adaptation for ENABLE/FAIL-SAFE logic; verify CMTI (75 kV/µs) suffices for target noise environment |
Compared with ADUM142E0BRZ-RL7, ADUM142D0BRZ-RL7 provides deterministic low-state fail-safe behavior critical for safety interlocks, while SI8640ED-B-IS offers higher isolation voltage but introduces layout and timing trade-offs not present in the Analog Devices solution.

FAQ
What is the isolation voltage rating of the ADUM142D0BRZ-RL7?
The ADUM142D0BRZ-RL7 has a rated dielectric insulation voltage of 3.0 kVRMS for 1 minute, compliant with UL 1577, IEC/EN/CSA 60950-1, and IEC 60601-1. This rating applies to the R-16 narrow-body SOIC package and is verified per DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation.
Does the ADUM142D0BRZ-RL7 support level translation between different supply voltages?
Yes, the ADUM142D0BRZ-RL7 supports independent 1.8 V to 5 V supplies on both sides (VDD1 and VDD2), enabling seamless level translation across the isolation barrier - for example, interfacing a 1.8 V FPGA I/O to a 3.3 V ADC SPI bus without external level shifters.
What does the 'D0' in ADUM142D0BRZ-RL7 indicate?
The 'D0' suffix identifies the fail-safe output configuration: when VDD1 is unpowered or DISABLE1 is asserted, all four outputs of the ADUM142D0BRZ-RL7 default to logic low. This differs from 'E0' variants, which default to logic high under the same conditions.
Is the ADUM142D0BRZ-RL7 qualified for automotive applications?
Yes, the ADUM142D0BRZ-RL7 is AEC-Q100 qualified for Grade 1 (−40°C to +125°C), making it suitable for automotive powertrain, battery management, and body electronics where extended temperature range and reliability are mandatory.
How does the ADUM142D0BRZ-RL7 handle common-mode transients?
The ADUM142D0BRZ-RL7 achieves 100 kV/µs common-mode transient immunity (CMTI), measured per IEC 61000-4-4. This allows it to maintain signal integrity in noisy environments such as motor drives and switch-mode power supplies where rapid voltage transients cross the isolation barrier.
