LT3960EMSE#TRPBF Overview
A CAN transceiver is an interface circuit that converts logic-level signals into a physical differential bus and receives bus states back into logic-level signals. The LT3960 uses the CAN physical layer as a rugged transport mechanism for an I2C-style single-master bus. Its protected line-fault inputs, extended common-mode capability, and internal regulator support integration where the I2C master and remote bus-powered nodes are separated by substantial cable distance or electrical noise.
Key verified features include operation up to 400 kbps, compatibility with 3.3 V and 5 V systems, protection from overvoltage line faults, and an internal 3.3 V regulator or selectable 5 V bus-voltage operation. Bidirectional communication is permitted, allowing data signals to flow between the host-side interface and the bus-side transceiver. The manufacturer identifies the LT3960EMSE as a 10-lead MSOP package, while the orderable LT3960EMSE#TRPBF suffix identifies the leaded RoHS-compliant packaging configuration.
The device is supplied from a single wide-ranging input supply, reducing system power-tree complexity when the interface must operate near higher-voltage industrial or automotive-related equipment. Its physical-layer approach is intended for extending a bus rather than replacing a conventional CAN controller. Designers should account for the MSOP exposed pad, line termination, common-mode environment, cable length, grounding, and the different logic and bus-side voltage domains.
Typical applications include industrial sensor links, remote instrumentation, building-automation equipment, noisy factory communication, and embedded systems that need I2C traffic to cross an electrically hostile cable. The verified manufacturer page specifically references the EVAL-LT3960-AZ evaluation circuit, which is useful for validating board routing, bus termination, and system behavior.
For PCB design, place the transceiver near the cable connector and preserve a controlled return path to reduce common-mode conversion. Confirm the exposed-pad connection and thermal pad layout against the manufacturer package drawing. Do not substitute a conventional CAN transceiver without checking logic-side voltage, timing, fault behavior, and pin compatibility.
This page combines the verified Analog Devices product information with practical interface-design guidance. It distinguishes the LT3960 from ordinary CAN controllers, emphasizes the 400 kbps single-master I2C role, and identifies which electrical details must be confirmed in the datasheet before layout release.

Typical Applications
LT3960EMSE#TRPBF is suitable for 6 applications: Industrial Sensor Bus Extension, Noisy Remote Instrumentation, Building Automation Networks, Embedded Control and Monitoring, Automotive-Related Test and Service Links, Evaluation and Communications Bring-Up.
Industrial Sensor Bus Extension
The LT3960EMSE#TRPBF is suitable for extending a single-master I2C sensor bus across a factory floor or between separated instrument compartments. Its 400 kbps communication rate preserves I2C-oriented timing while the CAN physical layer provides a more robust cable interface. The 60 V power-supply range can simplify interface integration near higher-voltage equipment, while overvoltage line-fault protection and extended common-mode capability help manage unpredictable cable conditions. Layout should keep the transceiver close to the connector and provide a controlled return path.
Recommended
Noisy Remote Instrumentation
The LT3960EMSE#TRPBF can bridge I2C traffic between an instrument and a remote sensor assembly when electromagnetic noise or ground-potential differences make a direct cable connection unreliable. Using the CAN physical layer, the device supports communication up to 400 kbps and permits bidirectional data flow. Its protected line inputs are useful where connected equipment may expose the bus to accidental overvoltage conditions. Cable shielding, common-mode reduction, and tested termination remain important at the system level.
Recommended
Building Automation Networks
The LT3960EMSE#TRPBF can extend a single-master I2C control bus to building-automation modules located beyond the original short I2C reach. Its 400 kbps rate is appropriate for moderate-speed command and status traffic, while the 60 V supply range helps interface with broader building equipment voltage domains. The transceiver should be selected only after checking whether the selected variant’s junction-temperature grade matches the installation environment and after validating cable length and fault-energy requirements.
Recommended
Embedded Control and Monitoring
The LT3960EMSE#TRPBF fits embedded monitoring systems that need to carry I2C traffic between a controller and a remote acquisition or conditioning module. The single-master architecture and 400 kbps limit keep the interface aligned with common embedded sensor buses, while the physical-layer protection features address the harsher conditions encountered outside the controller enclosure. Designers should separate logic-side and bus-side routing, use the manufacturer’s exposed-pad land pattern, and test startup behavior across power-supply conditions.
Recommended
Automotive-Related Test and Service Links
The LT3960 family can be evaluated for service and diagnostic links where I2C-compatible equipment must communicate across a noisy harness. The related LT3960JMSE#TRPBF has a verified -40°C to 150°C operating-junction-temperature guarantee, making it the more relevant candidate for elevated-temperature environments. The LT3960EMSE#TRPBF is specified to -40°C to 125°C. Neither part should be treated as an automotive-qualified device unless the relevant qualification documentation is separately verified.
Recommended
Evaluation and Communications Bring-Up
The LT3960EMSE#TRPBF is appropriate for a communications bring-up platform where engineers need to evaluate I2C-to-CAN physical-layer extension, remote cable behavior, and line-fault tolerance. Analog Devices specifically references the EVAL-LT3960-AZ evaluation circuit and provides an evaluation-hardware page. The device can be used to validate the 400 kbps communication path, bidirectional data flow, power arrangement, and PCB layout before integrating it into a larger instrument or sensor network.

Key Differentiators
- Same-family higher-temperature alternative (vs LT3960JMSE#TRPBF)
- I2C-to-CAN physical-layer positioning (vs SN75176BD)
- Verified 400 kbps operation (vs Conventional CAN transceivers)
Design Notes
Place the LT3960 close to the external bus connector so the protected line interface and cable-side return path are kept short. Follow the manufacturer’s MSOP exposed-pad land pattern and confirm whether the pad is electrically tied, thermally connected, or both for the specific package variant. Keep the logic-side I2C traces away from the bus-side line and shield connection to reduce coupling into sensitive control signals.
The verified operating point is up to 400 kbps, so preserve a continuous return path and use the bus termination strategy specified by the manufacturer application guidance. Shielding and grounding can reduce externally induced noise, but they do not replace proper common-mode control. Test the complete cable length, connector transitions, grounding arrangement, and both power states because the I2C logic side and CAN physical side may use different voltage domains.
Do not treat LT3960 as a conventional CAN controller or assume that every 10-pin CAN transceiver is interchangeable. Confirm the exact pin names, shutdown behavior, supply limits, regulator configuration, absolute maximum ratings, and exposed-pad connection in the Analog Devices datasheet. In particular, LT3960EMSE is specified to -40°C to 125°C, while the related LT3960J has a different junction-temperature guarantee.
Compliance Information
The verified DigiKey and Mouser listings identify the TRPBF ordering code as leaded RoHS-compliant packaging. RoHS, REACH, halogen-free, conflict-minerals, and automotive qualification information beyond the explicit TRPBF designation was not supplied.
