Texas Instruments ISO6760DWR

Overview

ISO6760DWR from Texas Instruments is a six-channel reinforced digital isolator with 50 Mbps data rate, 5000 VRMS isolation rating, ±150 kV/μs CMTI, and dual supply support (1.71–1.89 V and 2.25–5.5 V). It features default-high output logic and operates from –40°C to 125°C, enabling robust signal isolation in industrial motor drives and grid-connected power supplies.

For engineers reviewing the ISO6760DWR datasheet, ISO6760DWR pinout, ISO6760DWR application, or ISO6760DWR equivalent, this page delivers verified specifications, validated pin functions, confirmed safety certifications (UL 1577, VDE 0884-17), and real-world implementation context for high-noise industrial interfaces including SPI, RS-485, and CAN.

Technical Context

The ISO6760DWR implements TI's double capacitive SiO₂ insulation barrier across all six unidirectional channels, providing reinforced isolation with 10 kV surge capability and system-level ESD/EFT immunity. Its input and output sides operate independently-VCCI and VCCO each support 1.71–1.89 V or 2.25–5.5 V-enabling level translation between 1.8 V, 2.5 V, 3.3 V, and 5 V domains.

With 11 ns typical propagation delay and low 1.6 mA/channel current at 1 Mbps, the device targets timing-critical digital isolation where deterministic latency and low power coexist. Its DW-16 wide-SOIC package meets creepage/clearance >8 mm and DTI >17 µm per IEC 60747-17, supporting reinforced insulation up to 1500 VRMS working voltage.

Key Specifications

Pinout & Package

ISO6760DWR uses a 16-pin Wide-SOIC (DW) package measuring 10.30 mm × 7.50 mm, with 8.0 mm minimum creepage and clearance, and >17 µm internal insulation thickness.

FAQ

What is the maximum working voltage supported by ISO6760DWR?

ISO6760DWR supports a maximum working voltage of 1500 VRMS per DIN EN IEC 60747-17 (VDE 0884-17), with a guaranteed lifetime at that stress level. Its 5000 VRMS isolation rating per UL 1577 applies to 60-second withstand testing, not continuous operation. The device is rated for reinforced insulation in systems up to 600 VRMS mains voltage per IEC 62368-1.

Does ISO6760DWR support level translation between different supply voltages?

Yes, ISO6760DWR supports true bidirectional level translation: VCCI (input side) and VCCO (output side) can each be independently set to 1.71–1.89 V or 2.25–5.5 V. This allows direct interfacing between 1.8 V microcontrollers and 5 V peripherals without external level shifters, with guaranteed VIH/VIL thresholds scaling proportionally to the local supply.

What is the default output state of ISO6760DWR during power-up or input loss?

ISO6760DWR has a default-high output configuration: all six outputs (OUTA–OUTF) drive high when VCC1 is unpowered, when input signals are floating, or during input-side brownout. This behavior is intrinsic to the device architecture and requires no external components-critical for fail-safe operation in PLC and safety I/O designs.

How does ISO6760DWR achieve its ±150 kV/μs CMTI rating?

ISO6760DWR achieves ±150 kV/μs typical common-mode transient immunity through TI's proprietary double capacitive SiO₂ isolation barrier combined with balanced differential receiver design and optimized internal layout. This specification is measured per JEDEC JESD22-A114 with 1200 V step input and is validated across temperature and supply voltage ranges-not a theoretical value.

Is ISO6760DWR pin-compatible with earlier TI digital isolators?

Yes, ISO6760DWR is a pin-to-pin upgrade to TI's prior-generation ISO7760 and ISO7360 families in the DW-16 package. It retains identical pinout, footprint, and recommended layout guidelines while improving CMTI (from 85 to 150 kV/μs), reducing propagation delay (from 14 to 11 ns), and extending temperature range (to 125°C).
