Product details
Overview
ISO7710DWR from Texas Instruments is a reinforced single-channel digital isolator with 5000VRMS isolation rating (DW package), 100Mbps data rate, ±100kV/μs CMTI, and dual 2.25V–5.5V supply operation. It provides galvanic signal isolation between microcontroller I/O and high-noise motor drive or power supply control circuits.
For engineers reviewing the ISO7710DWR datasheet, ISO7710DWR pinout, ISO7710DWR application, or ISO7710DWR equivalent, key selection criteria include reinforced insulation certification (VDE 0884-17, UL 1577), DW-16 SOIC package dimensions (10.30mm × 7.50mm), default-high output behavior, and compatibility with RS-485, CAN, and isolated gate driver interfaces.
Technical Context
The ISO7710DWR implements double capacitive SiO₂ barrier isolation with separate VCC1/GND1 and VCC2/GND2 domains, enabling level translation across the barrier. Its logic input/output buffers are decoupled by robust dielectric insulation rated for >30-year lifetime at 1500VRMS working voltage.
It features integrated undervoltage lockout (UVLO) with 100–200mV hysteresis and failsafe default output (high for non-F suffix parts) upon VCC1 loss. EMC robustness is achieved via layout-optimized capacitive coupling and system-level ESD/EFT/surge immunity per IEC 61000-4-2 (±8kV contact discharge).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 100 Mbps maximum - supports high-speed serial links like isolated SPI, RS-485, and CAN FD without timing bottlenecks. |
| Isolation Rating | 5000 VRMS (UL 1577) - enables safe operation in industrial mains-connected equipment up to 1000 VRMS systems. |
| CMTI | ±100 kV/μs typical - rejects fast common-mode transients in motor drives and inverters without signal corruption. |
| Propagation Delay | 11 ns typical (5V) - ensures tight timing alignment in real-time control loops and synchronized sampling applications. |
| Supply Range | 2.25 V to 5.5 V per side - allows direct interfacing with 3.3V MCUs and 5V peripherals without level shifters. |
| Operating Temp | –55°C to +125°C - qualified for under-hood automotive, solar inverter, and industrial PLC environments. |
| Surge Capability | 12.8 kV peak (oil test) - withstands lightning-induced surges in outdoor power electronics and grid-tied systems. |
Pinout & Package
ISO7710DWR uses the wide-body 16-pin SOIC (DW) package (10.30 mm × 7.50 mm body size, 10.30 mm × 10.30 mm overall). Pinout is optimized for creepage/clearance compliance: primary-side pins (VCC1, GND1, IN) occupy left half; secondary-side pins (VCC2, GND2, OUT) occupy right half; NC pins isolate domains.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC1 | Primary-side power supply | Supplies input buffer and isolation logic; UVLO threshold 2.25 V (rising), 1.8 V (falling). |
| GND1 | Primary-side ground reference | Return path for VCC1 domain; must be separated from GND2 by ≥8 mm PCB clearance. |
| IN | Digital input signal | CMOS/LVCMOS-compatible; VIH = 0.7×VCC1, VIL = 0.3×VCC1; no external pull-up required. |
| VCC2 | Secondary-side power supply | Supplies output buffer; independent of VCC1 - enables level translation (e.g., 3.3V IN → 5V OUT). |
| GND2 | Secondary-side ground reference | Return path for VCC2 domain; galvanically isolated from GND1; defines output logic reference. |
| OUT | Digital output signal | Default-high on VCC1 loss; VOH = VCC2 – 0.4 V (5V), VOL = 0.4 V (5V); drives 15 pF load at 100 Mbps. |
Key Features
| Feature | Design Value |
|---|---|
| Reinforced Isolation Certification | VDE 0884-17 (DIN EN IEC 60747-17), UL 1577, IEC 62368-1 - meets safety requirements for medical (2 MOPP), industrial, and EV charging systems. |
| High CMTI Performance | ±100 kV/μs typical - prevents data errors during rapid bus voltage transients in motor phase-leg switching. |
| Low Power at High Speed | 7.4 mA total (ICC1 + ICC2) at 100 Mbps / 5V - reduces thermal load in dense PCB layouts and fanless enclosures. |
| Fail-Safe Default Output | Output remains high after VCC1 dropout (tDO = 0.3 μs max) - maintains safe state in controller fault conditions. |
| Wide Supply Compatibility | Operates from 2.25V to 5.5V on both sides - eliminates need for external regulators when interfacing mixed-voltage subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM110N0BRZ | Single-channel, 150 Mbps, 3750 VRMS (reinforced), SOIC-8 package, 2.7–5.5 V supply. | Lacks VDE 0884-17 certification; lower surge rating (6.5 kV); no 2.25V operation. | Choose ADUM110N0BRZ only if higher speed is critical and safety certifications are not required. |
| SI8610BB-B-IS | Single-channel, 100 Mbps, 5000 VRMS (UL/VDE), SOIC-8 package, 2.5–5.5 V supply, default-low output. | SOIC-8 footprint (4.9 × 3.91 mm) vs. ISO7710DWR's SOIC-16 (10.3 × 7.5 mm); no 2.25V support; F-suffix behavior only. | Choose SI8610BB-B-IS for space-constrained designs where SOIC-8 is mandated and default-low logic suffices. |
Compared with ADUM110N0BRZ and SI8610BB-B-IS, ISO7710DWR uniquely combines VDE-reinforced certification, 2.25V minimum supply, SOIC-16 creepage margin, and default-high fail-safe behavior - making it optimal for safety-critical industrial and medical power systems requiring long-term reliability validation.

FAQ
What is the isolation rating and certification status of ISO7710DWR?
ISO7710DWR has a 5000 VRMS isolation rating per UL 1577 and is certified to VDE 0884-17 (DIN EN IEC 60747-17), IEC 62368-1, IEC 60601-1 (2 MOPP), and GB 4943.1. These certifications validate its reinforced insulation for use in medical, industrial, and grid-connected equipment where safety-critical isolation is mandated.
Does ISO7710DWR support level translation between different supply voltages?
Yes, ISO7710DWR supports true bidirectional level translation: VCC1 can operate from 2.25 V to 5.5 V independently of VCC2, which also ranges from 2.25 V to 5.5 V. This allows clean interfacing between 3.3 V microcontrollers and 5 V peripheral buses without external level shifters - a capability confirmed in the device's recommended operating conditions table.
What is the default output state of ISO7710DWR during power loss?
ISO7710DWR has a default-high output configuration. When VCC1 drops below UVLO threshold (≤1.8 V), the output transitions to and holds high within 0.3 μs. This fail-safe behavior is intrinsic to the non-F suffix variant and is documented in the Device Functional Modes section of the ISO7710DWR datasheet.
Can ISO7710DWR be used in CAN bus isolation applications?
Yes, ISO7710DWR is explicitly cited in TI's application documentation for CAN bus isolation. Its ±100 kV/μs CMTI, low propagation delay (11 ns), and robust EMC immunity make it suitable for isolating CAN transceivers in noisy motor control and automotive subsystems - provided an isolated power supply is used for VCC2.
What package type and dimensions does ISO7710DWR use?
ISO7710DWR uses the wide-body 16-pin SOIC (DW) package with nominal body dimensions of 10.30 mm × 7.50 mm and overall outline of 10.30 mm × 10.30 mm. This package provides 8 mm creepage and clearance - exceeding IEC 60664-1 requirements for reinforced insulation at 1500 VRMS working voltage.
