ISO7763DWR - 6-Channel 100Mbps Reinforced Digital Isolator | TI
MPN: ISO7763DWR ✓ Hoạt độngISO7763DWR Tóm tắt
A digital isolator is a semiconductor interface that transfers data across an electrically isolated barrier while minimizing conductive and capacitive coupling between its input and output sides. The ISO7763 belongs to the interface-IC hierarchy and uses capacitive isolation to support signal transmission up to 100 Mbps. Its reinforced isolation rating is intended for applications requiring stronger galvanic separation than basic isolation circuits.
The ISO7763DWR provides six digital channels in a 3/3 arrangement, allowing three signals to travel in one direction and three in the opposite direction. Its 5000 Vrms DW-package isolation rating, 85 kV/us common-mode transient immunity, and reinforced construction make it suitable for industrial control, power conversion, communications, and test equipment. The device is specified from -55°C to +125°C according to the manufacturer product details.
The principal design considerations are correct supply bypassing, respect for the isolation barrier, propagation-delay behavior, and the package creepage and clearance requirements. The 16-SOIC package is compatible with surface-mount assembly, while the exact pin functions and channel direction must be confirmed from the official datasheet before PCB routing. The default output state of ISO7763DWR is HIGH, which should be considered during power-up and fail-safe system design.
Typical applications include isolated SPI or control links in power converters, communication interfaces in industrial equipment, protection between high-side and low-side circuitry, and digital signal isolation between systems with different ground references. Because isolation does not remove the need for careful layout, external protection, and common-mode analysis, the ISO7763DWR should be selected based on voltage, speed, timing, and EMC requirements rather than package appearance alone.
This page consolidates the verified ISO7763DWR specifications, package information, sourcing links, and practical selection guidance. It is intended to help engineers identify whether the ISO7763DWR is appropriate for a particular isolated-interface design.

Ứng dụng tiêu biểu
ISO7763DWR phù hợp cho 6 Áp dụngs: Industrial Control Signal Isolation, Power Converter Control Interface, High-Speed Communication Equipment, Test and Measurement Systems, Motor and Gate-Driver Control, Protected Data Acquisition Systems.
Industrial Control Signal Isolation
ISO7763DWR fits industrial control systems that need to connect a controller to field-side logic across a reinforced isolation barrier. Its six-channel 3/3 architecture can carry multiple control and feedback signals, while the 100 Mbps maximum data rate supports fast digital handshakes. The 5000 Vrms isolation rating and 85 kV/us CMTI specification help the interface withstand electrical separation requirements. Keep the isolation boundary, creepage, and clearance layout compliant with the TI datasheet and system safety requirements.

Power Converter Control Interface
ISO7763DWR can isolate PWM-control and feedback signals between a power controller and switching circuitry. The 3/3 channel arrangement supports bidirectional digital communication, while the 100 Mbps capability provides margin for high-frequency control traffic. Its reinforced isolation is useful when the controller and power stage operate at different voltage domains. The designer must still verify propagation delay, supply levels, layout spacing, and any requirements for isolated bias power.
Được đề xuất
High-Speed Communication Equipment
ISO7763DWR is suitable for digital communication links where low-voltage electronics must communicate with a separate ground domain. Its maximum data rate of 100 Mbps allows the device to carry fast control, status, or framing signals rather than only slow optocoupler-compatible traffic. The 85 kV/us CMTI figure supports transient robustness, but actual signal integrity depends on edge rates, traces, terminations, and grounding. Validate channel direction and supply requirements against the official datasheet.
Được đề xuất
Test and Measurement Systems
ISO7763DWR can be used in test equipment to separate sensitive digital control or measurement paths from high-energy or externally exposed circuitry. The six-channel 3/3 arrangement provides flexibility for command and return paths, and the 100 Mbps rating supports automated digital sequencing. The wide -55°C to +125°C temperature specification supports demanding industrial and laboratory environments. Isolation capability must be paired with appropriate PCB creepage, clearance, insulation, and safety assessment.
Được đề xuất
Motor and Gate-Driver Control
ISO7763DWR can provide digital isolation in motor-control or isolated-driver systems where command signals cross a high-side-to-low-side barrier. The high-speed channels can accommodate timing-sensitive control information, while reinforced isolation helps separate the domains. It does not replace the gate driver itself or provide motor power; those functions must be implemented separately. Confirm propagation-delay limits, channel mapping, supply voltages, and layout requirements for the selected motor-control topology.
Được đề xuất
Protected Data Acquisition Systems
ISO7763DWR is useful between a data-acquisition front end and a processing system when the two sections share no common ground or operate across a substantial voltage barrier. Six isolated channels can transfer clock, control, and status information while maintaining up to 100 Mbps communication. The reinforced 5000 Vrms isolation specification is a device rating, not a guarantee that every completed product meets a safety standard. Apply the appropriate creepage, clearance, insulation, and transient-protection design rules.

Ghi chú thiết kế
Preserve the manufacturer-defined isolation barrier and all required creepage and clearance distances in the PCB stackup. Keep primary-side and secondary-side components, copper, and test pads on their respective sides of the barrier. Because the ISO7763DWR is a 16-SOIC DW package, verify the land pattern and pin numbering against the TI mechanical drawing before release to fabrication.
Do not substitute ISO7763FDWR without checking default output behavior. The retrieved TI engineering discussion states that ISO7763DWR defaults HIGH and ISO7763FDWR defaults LOW. That difference can affect power-up states, fault containment, and software-visible logic even when the broader device family and package appear similar.
Use the full data-rate and timing budget of the TI datasheet when designing around the 100 Mbps capability. Account for channel direction, propagation delay, load capacitance, edge rate, output loading, and the receiving device's input threshold. PCB traces should be short and appropriately terminated where required; isolation reduces ground coupling but does not automatically solve signal-integrity problems.
Thông tin tuân thủ
The retrieved technical data references UL 1577 isolation ratings for the ISO776x family, but the supplied data does not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Verify current compliance documents with Texas Instruments or the authorized distributor.
