Product details
Overview
ADUM141D1BRZ-RL7 from Analog Devices is a quad-channel digital isolator based on iCoupler® transformer technology, providing 3.0 kVRMS galvanic isolation between two independent 2-channel logic domains. 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 ADUM141D1BRZ-RL7 datasheet, ADUM141D1BRZ-RL7 pinout, ADUM141D1BRZ-RL7 application, or ADUM141D1BRZ-RL7 equivalent, key selection criteria include common-mode transient immunity (100 kV/µs), AEC-Q100 qualification, SOIC_N-16 package footprint, and fail-safe high output configuration specific to the D1 variant.
Technical Context
The ADUM141D1BRZ-RL7 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-this D1 variant asserts high on input power loss or disable assertion. The device complies with DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 3.0 kVRMS for 1 minute - meets UL 1577 and IEC 60950-1 safety requirements for reinforced insulation |
| Max Data Rate | 150 Mbps - guarantees reliable high-speed serial communication in SPI and digital interface applications |
| Propagation Delay | 13 ns max at 5 V - enables timing-critical control loops and fast feedback systems |
| Common-Mode Transient Immunity | 100 kV/µs - sustains signal integrity in noisy motor drive or power converter environments |
| Supply Voltage Range | 1.8 V to 5 V per side - supports mixed-voltage system interfacing and level translation across isolation barrier |
| Fail-Safe Output State | High - outputs default to logic high during VDD1 loss or DISABLE1 assertion, critical for safe system shutdown |
| Operating Temperature | −40°C to +125°C - qualified for automotive under-hood and industrial ambient conditions |
Pinout & Package
ADUM141D1BRZ-RL7 is housed in a RoHS-compliant 16-lead narrow-body SOIC (SOIC_N-16) package with 7.62 mm body width and 1.27 mm pitch. Creepage and clearance meet 4.0 mm minimum per IEC 60950-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Primary-side power supply | Supplies input-side logic and isolation transmitter; must be 1.8–5 V |
| GND1 | Primary-side ground reference | Return path for VDD1; must be isolated from GND2 by PCB layout |
| INA, INB | Input channels A and B | Accept CMOS-level signals from controller side; drive internal transformers |
| DIS1 | Input disable control | Pull high to force INA/INB outputs into high-impedance state; active-low logic |
| VDD2 | Secondary-side power supply | Supplies output-side logic and isolation receiver; independent of VDD1 |
| GND2 | Secondary-side ground reference | Return path for VDD2; galvanically isolated from GND1 |
| OUTA, OUTB | Output channels A and B | Deliver isolated, fail-safe-high logic outputs to peripheral side (e.g., ADC, DAC) |
| VE2 | Output enable control | Pull low to enable OUTA/OUTB; open-drain compatible with pull-up to VDD2 |
Key Features
| Feature | Design Value |
|---|---|
| iCoupler® transformer isolation | Eliminates LED aging and CTR degradation of optocouplers; enables >50-year lifetime at 125°C |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8641ED-B-IS | Capacitive isolation; 3.75 kVRMS; 150 Mbps; SOIC_W-16 package | Wider 7.8 mm creepage supports higher working voltages; no AEC-Q100 qualification | Select when higher isolation voltage or extended creepage is required, but automotive qualification is not needed. |
| ISO6741QDWR | Capacitive isolation; 3.0 kVRMS; 50 Mbps; SOIC-16; AEC-Q100 Grade 1 | Lower data rate limits SPI clock to ≤12.5 MHz; lower CMTI (42 kV/µs) | Choose for cost-sensitive automotive applications where 150 Mbps is unnecessary and CMTI >75 kV/µs is not mandated. |

FAQ
What is the fail-safe output behavior of ADUM141D1BRZ-RL7?
The ADUM141D1BRZ-RL7 is a D1 variant, meaning its outputs default to logic high when VDD1 is absent or when the DIS1 input is asserted high. This behavior ensures safe system states during power faults or controller resets, and is confirmed in the Ordering Guide and Truth Tables section of Rev. K datasheet.
Does ADUM141D1BRZ-RL7 support 1.8 V operation on both sides?
Yes, ADUM141D1BRZ-RL7 supports 1.8 V to 5 V operation independently on VDD1 and VDD2. Electrical Characteristics tables for 1.8 V operation (Table 7) confirm full functionality-including 150 Mbps data rate and 15 ns max propagation delay-at 1.8 V on either or both supplies.
What safety certifications does ADUM141D1BRZ-RL7 hold?
ADUM141D1BRZ-RL7 is certified to UL 1577 (3000 VRMS), 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), with VIORM = 565 V peak and reinforced insulation per package-level test data in Tables 9–11.
Is ADUM141D1BRZ-RL7 pin-compatible with earlier ADuM140x devices?
No-ADUM141D1BRZ-RL7 is not pin-compatible with ADuM1400/ADuM1401. The datasheet explicitly states only ADuM140E1/ADuM141E1/ADuM142E1 variants are pin-compatible with those legacy parts. ADUM141D1BRZ-RL7 uses a different pinout optimized for D1 fail-safe configuration.
What is the maximum guaranteed data rate for ADUM141D1BRZ-RL7?
The maximum guaranteed data rate for ADUM141D1BRZ-RL7 is 150 Mbps, as specified in Switching Specifications tables across all supply voltages (Tables 1, 3, 5, 7). Higher rates may function but are not production-tested or warranted.
