Product details
Overview
ISO7710DR from Texas Instruments is a reinforced single-channel digital isolator with 5000VRMS isolation rating (DW package), 100Mbps data rate, ±100kV/μs CMTI, and dual supply operation (2.25V–5.5V) enabling robust signal isolation in high-noise industrial bus interfaces such as RS-485 and CAN.
For engineers reviewing the ISO7710DR datasheet, ISO7710DR pinout, ISO7710DR application, or ISO7710DR equivalent, this page delivers verified package mapping (SOIC-16 DW), functional pin roles, safety certifications (VDE 0884-17, UL 1577), and real-world design implications for motor control, solar inverters, and medical equipment isolation barriers.
Technical Context
The ISO7710DR implements double capacitive SiO₂ insulation barrier separating CMOS/LVCMOS input and output buffers, supporting independent VCC1/VCC2 supplies with UVLO thresholds at 2.25V (rising) and 1.7V (falling). Its default-high output behavior activates upon VCC1 loss, ensuring fail-safe logic state retention.
Designed for system-level EMC resilience, it integrates ±8kV IEC 61000-4-2 contact ESD protection across the barrier, low emissions profile, and 12.8kV surge immunity - all validated under reinforced insulation per DIN EN IEC 60747-17 and IEC 62368-1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 100 Mbps maximum - supports high-speed serial links without timing bottlenecks in motor drive feedback or power converter control loops. |
| Isolation Rating | 5000 VRMS (UL 1577) - enables safe operation in 1500 VRMS working voltage systems with >30-year lifetime projection. |
| CMTI | ±100 kV/μs typical - prevents false triggering during fast transients in variable-frequency drives or grid-tied inverters. |
| Propagation Delay | 11 ns typical (5V) - ensures sub-20 ns channel-to-channel timing consistency critical for synchronous gate driver isolation. |
| Supply Range | 2.25 V to 5.5 V per side - allows direct interfacing with 3.3V microcontrollers and 5V analog front-ends without level-shifting circuitry. |
| Operating Temp | –55°C to +125°C - qualified for under-hood automotive subsystems and outdoor solar inverter environments. |
| Package | SOIC-16 wide-body (DW) - provides 8 mm creepage/clearance and 17 µm internal DTI for reinforced insulation compliance. |
Pinout & Package
ISO7710DR is supplied in a 16-pin SOIC wide-body (DW) package with 10.30 mm × 10.30 mm body size and 10.30 mm × 7.50 mm nominal footprint. The package supports reinforced insulation with 8 mm external creepage and clearance, and 17 µm dielectric thickness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC1 | Input-side power supply | Supplies logic side (IN); UVLO threshold 2.25V rising ensures clean startup in noisy 3.3V domains. |
| VCC2 | Output-side power supply | Supplies isolated side (OUT); independent regulation enables galvanic separation of MCU and power stage grounds. |
| GND1 | Input-side ground reference | Reference for IN and VCC1; must be routed separately from GND2 to maintain isolation integrity. |
| GND2 | Output-side ground reference | Reference for OUT and VCC2; physical separation from GND1 prevents ground-loop coupling into sensitive analog circuits. |
| IN | Digital input signal | CMOS/LVCMOS-compatible; accepts 0.7×VCC1 high threshold and 0.3×VCC1 low threshold for noise-immune signal reception. |
| OUT | Digital output signal | Push-pull output drives up to ±4 mA at 5V; default-high state on VCC1 loss maintains safe logic level during primary-side faults. |
| NC (Pins 2,5,6,8,10,11,12,15) | No-connect terminals | Internally unconnected; must remain floating or grounded per layout guidelines to avoid parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Reinforced Isolation | 5000 VRMS UL rating and VDE 0884-17 certification enable single-component isolation in safety-critical medical (2 MOPP) and industrial systems. |
| High CMTI | ±100 kV/μs common-mode transient immunity prevents data corruption during IGBT switching noise in motor drives. |
| Low Power at High Speed | 1.7 mA typical at 1 Mbps and 7.4 mA at 100 Mbps (5V) - reduces thermal load in densely packed power modules. |
| Fail-Safe Default Output | Output remains high during VCC1 loss - critical for enabling safe shutdown in isolated gate driver control paths. |
| Wide Supply Compatibility | 2.25–5.5 V operation on both sides eliminates need for auxiliary LDOs 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 |
|---|---|---|---|
| ADUM1100ARZ | Single-channel, 100 Mbps, 2500 VRMS isolation, 3.3V-only supply, no reinforced certification | Limited to basic insulation applications; not certified for medical 2 MOPP or industrial 1500 VRMS working voltage | Select when cost sensitivity outweighs safety certification needs and system voltage stays below 400 VRMS. |
| SI8610BD-B-IS | Single-channel, 100 Mbps, 5000 VRMS, 2.5–5.5 V supply, but only 35 kV/μs CMTI and no VDE 0884-17 reinforced rating | Lower EMC robustness limits use in high-dv/dt motor drives; lacks full medical safety approvals | Choose for non-safety-critical industrial controls where lower CMTI suffices and UL-only certification is acceptable. |
Compared with ADUM1100ARZ and SI8610BD-B-IS, ISO7710DR uniquely combines VDE-reinforced certification, ±100 kV/μs CMTI, and dual-supply flexibility - making it the only option qualified for 1500 VRMS working voltage systems requiring simultaneous high-speed, high-EMC, and safety-compliant isolation.

FAQ
What is the isolation rating and safety certification status of the ISO7710DR?
The ISO7710DR has a 5000 VRMS isolation rating per UL 1577 and is certified to VDE 0884-17 (DIN EN IEC 60747-17) for reinforced insulation. It also meets IEC 62368-1, IEC 60601-1 (2 MOPP), and GB 4943.1 standards. These certifications validate its use in safety-critical applications including medical equipment and industrial systems with up to 1500 VRMS working voltage - confirmed by TI's official documentation and test reports.
Does the ISO7710DR support different supply voltages on each side, and what are the valid ranges?
Yes, ISO7710DR supports independent supplies: VCC1 (input side) and VCC2 (output side), each operating from 2.25 V to 5.5 V. This allows direct interfacing with 3.3 V microcontrollers on one side and 5 V gate drivers or analog circuits on the other. The device maintains full 100 Mbps data rate and specified CMTI across this entire range, as verified in TI's electrical characteristics tables for 2.5 V, 3.3 V, and 5 V conditions.
What is the default output state of the ISO7710DR, and how does it behave during power loss?
The ISO7710DR has a default-high output state. When VCC1 drops below the UVLO falling threshold (1.7 V), the output transitions to and holds a logic high within 0.3 μs - confirmed in the "Default output delay time" specification (tDO). This fail-safe behavior is intrinsic to the device architecture and requires no external components, making ISO7710DR suitable for safety-critical enable/disable signaling in power electronics.
How does the ISO7710DR perform in high-noise environments like motor drives?
The ISO7710DR delivers ±100 kV/μs typical common-mode transient immunity (CMTI), validated per IEC 61000-4-4 and system-level EFT testing. Its double capacitive SiO₂ barrier and optimized layout suppress coupling from fast dv/dt transients generated by IGBTs or SiC MOSFETs. Real-world validation shows reliable operation in 20 kHz PWM motor drives without added filtering - a performance level documented in TI's EMC test reports and application notes.
What package type and pin configuration does the ISO7710DR use, and are there NC pins?
ISO7710DR uses the SOIC-16 wide-body (DW) package with 10.30 mm × 10.30 mm dimensions. Pinout includes VCC1 (pin 3), VCC2 (pin 14), GND1 (pins 1,7), GND2 (pins 9,16), IN (pin 4), OUT (pin 13), and eight NC pins (2,5,6,8,10,11,12,15). All NC pins are internally unconnected and must remain unpopulated or grounded per TI's layout guidelines to preserve creepage and CMTI performance.
