LT3960JMSE#TRPBF Übersicht
An I2C-to-CAN transceiver is an interface IC that translates the logic-level clock and data signals of a single-master I2C bus into a differential CAN physical-layer signal. The LT3960 extends that bus beyond a local circuit board, using two devices in a typical system: one connects near the I2C master, while the other provides the remote endpoint. This architecture preserves the familiar I2C host interface while gaining the noise immunity and fault tolerance associated with CAN cabling.
Key verified features include operation up to 400 kbps, compatibility with both 3.3 V and 5 V systems, a 60 V power-supply range for the CAN-side protection circuitry, and internal 3.3 V regulation. The receiver has a wide common-mode range of ±25 V or ±36 V depending on VCC. The LT3960 is designed for extended temperature-grade industrial environments; the manufacturer states that LT3960J performance is assured over a -40 °C to 150 °C operating junction range.
The exposed-pad MSOP package helps remove heat from the device when the CAN-side dissipation is significant. Placement should keep the transceiver close to the connector or cable entry, while the I2C master and local digital ground connections should remain isolated from the harsher CAN return path as appropriate. CAN termination and common-mode behavior must be evaluated for the complete bus rather than inferred from the IC alone.
Typical applications include remote sensor nodes, industrial monitoring links, building-control gateways, actuator networks, and embedded systems that need to extend I2C across a noisy cable. The 400 kbps rate is suitable for moderate-speed control and telemetry traffic, not high-bandwidth data transfer. The device should be selected only when its CAN common-mode, fault-protection, supply, and thermal characteristics match the target bus.
The most important design check is system-level compatibility: verify the 3.3 V or 5 V I2C levels, cable length and topology, termination strategy, grounding, and the maximum junction temperature. The LT3960’s protected CAN interface can simplify remote-bus deployment, but it does not eliminate the need for correct bus protection and wiring.

Typische Anwendungen
LT3960JMSE#TRPBF ist geeignet für 6 Anwendungs: Industrial Sensor Backbone, Building-Control Gateway, Remote Actuator Network, Environmental Monitoring Node, Embedded Test Fixture, Industrial Controller Expansion.
Industrial Sensor Backbone
The LT3960JMSE#TRPBF is well suited to carrying remote sensor data from a single-master I2C controller across a noisy industrial cable. Its 400 kbps maximum rate is ample for temperature, pressure, vibration, and status telemetry, while the CAN physical layer provides a differential signal path. Place one transceiver at the I2C master and another at the remote endpoint, then validate termination, grounding, and fault behavior for the installation.
Empfohlen
Building-Control Gateway
In a building-control gateway, the LT3960 can connect an I2C sensor cluster to a CAN-based supervisory network without requiring the cable to remain short. The 3.3 V and 5 V compatibility supports common controller supply arrangements, while the 60 V CAN-side power-supply range supports protected remote interfaces. The design must still account for cable length, ground offsets, surge exposure, and the system’s required communication profile.
Empfohlen
Remote Actuator Network
The LT3960JMSE#TRPBF can bridge a local I2C command structure to remote actuators through a CAN physical layer. At up to 400 kbps, it is appropriate for configuration, position, valve, or motor-status information where deterministic moderate-speed communication matters more than high payload throughput. Use protected connectors and validate actuator grounding so that motor or relay switching noise does not degrade the I2C-side control logic.
Empfohlen
Environmental Monitoring Node
A remote environmental monitor can use the LT3960 to carry I2C sensor data over a longer cable between a sensing head and a central controller. The transceiver’s differential CAN interface is useful where motor drives, relays, or switching supplies create electrical noise near the sensor wiring. The 400 kbps ceiling keeps the design focused on telemetry and alarms, while the wide receiver common-mode range helps accommodate ground-potential differences in distributed installations.
Empfohlen
Embedded Test Fixture
The LT3960 is useful in automated test fixtures that place a controller’s I2C interface several meters from a remote instrument or device under test. Instead of relying on a fragile point-to-point I2C cable, the fixture can use the CAN physical layer for a more robust differential connection. The 400 kbps rate supports test commands and measurement results, and the integrated line-fault protection helps manage accidental cable faults when the fixture is repeatedly connected and disconnected.
Empfohlen
Industrial Controller Expansion
The LT3960JMSE#TRPBF can extend a controller’s I2C peripheral bus to a remote expansion module when a short PCB-level bus is no longer practical. It is especially useful where the expansion board must communicate across a noisy harness while the host continues to use familiar SDA and SCL signaling. The design should define connector pinout, shield or drain strategy, termination, and fault current limits before the remote cable leaves the controller enclosure.

Wichtigste Unterscheidungsmerkmale
- Direct I2C-to-CAN bridge (vs. SN75176BD)
- Protected remote-bus interface (vs. LT3960JMSE#PBF)
- 3.3 V and 5 V system compatibility (vs. LT3960JMSE#WTRPBF)
Designhinweise
Place the LT3960 close to the CAN connector or cable entry, and route the differential CAN pair as a controlled pair with minimal stub length. Keep the I2C-side traces and local logic ground return on the appropriate side of the transceiver. The supplied manufacturer documentation identifies a two-device I2C-to-CAN arrangement, so the PCB should preserve the intended separation between local I2C signals and the external cable interface.
The MSOP exposed pad is an important thermal path and should be connected to the intended copper area according to the manufacturer layout guidance. Do not assume that the package can dissipate arbitrary CAN-side power without checking junction temperature, copper area, ambient temperature, and airflow. Estimated thermal calculations require the actual input voltage, load, package thermal resistance, and board construction, none of which are fully provided here.
A 400 kbps rating does not guarantee reliable communication over every cable length or topology. Verify termination, bus topology, grounding, common-mode behavior, connector protection, and the maximum external fault conditions before release. Also confirm the exact ordering suffix and pin mapping against the current Analog Devices datasheet; similar LT3960 suffix codes may represent packaging, temperature, or qualification differences.
Compliance-Informationen
The supplied manufacturer and distributor results do not provide verified RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements. The device is not classified as a power semiconductor, so SOA is not applicable.
