LT3960JMSE#PBF - 400kbps I2C-to-CAN Transceiver | ADI
MPN： LT3960JMSE#PBF ✓ 啟用中LT3960JMSE#PBF 概覽
An I2C-to-CAN transceiver is an interface IC that bridges the short-range, controller-oriented I2C bus and the CAN physical layer. It extends a single-master I2C connection through a harness or harsh electrical environment while preserving a familiar logic-side interface. In the system hierarchy, this device is an interface transceiver within CAN interface ICs and broader wired-communication semiconductors.
The verified information identifies 400 kbps I2C communication, a 60 V power-supply range, and internal 3.3 V operation. It also confirms protection from overvoltage line faults. The LT3960 family is intended for industrial communication, and the manufacturer states that LT3960J performance is guaranteed from -40°C to 150°C operating junction temperature; the broader datasheet also describes -40°C to 125°C operating-temperature assurance.
The receiver is a CAN-compatible differential receiver with a wide common-mode range of plus or minus 25 V or plus or minus 36 V, depending on VCC. In a typical two-device arrangement, one LT3960 is placed near the I2C master and the other near the distant endpoint. This arrangement keeps sensitive logic connections local while using the CAN physical layer for the longer link.
Typical uses include industrial sensor links, factory automation equipment, building-control modules, remote I/O nodes, and embedded systems that need an I2C master to communicate across a longer cable. Use the exposed-pad land pattern for thermal and electrical performance, and observe the manufacturer's pin and layout guidance.
A key design consideration is that the LT3960 is a transceiver, not a general-purpose CAN controller. The connected microcontroller must generate the appropriate bus behavior and protocol, while the LT3960 provides the physical signaling interface. Verify voltage ratings, termination, grounding, and fault conditions against the manufacturer datasheet.
This page combines verified distributor and manufacturer information with package, application, and design guidance intended to support faster sourcing and design review.

典型應用
LT3960JMSE#PBF 適用於 7 應用s: Industrial Sensor Cabling, Factory Automation Remote I/O, Building Control Networks, Remote Environmental Monitoring, Embedded Equipment Communication, Instrumentation and Test Systems, Automotive and Heavy Equipment Links.
Industrial Sensor Cabling
The LT3960JMSE#PBF fits an industrial sensor extension where a controller must carry I2C information beyond the short reach normally associated with the logic bus. The interface supports communication up to 400 kbps and uses CAN physical-layer signaling, allowing one unit near the master and another near the remote sensor node. Its verified protection from overvoltage line faults is useful where the cable may encounter electrical transients, although the exact protection and operating limits must still be checked against the Analog Devices datasheet.
推薦
Factory Automation Remote I/O
For a factory remote-I/O module, the LT3960JMSE#PBF can provide a defined path between a local embedded controller and a remote node while preserving an I2C-style host interface. Its 400 kbps capability is suitable for control and monitoring traffic that does not require a high-rate CAN protocol payload. Place the transceiver close to the cable connector, observe the exposed-pad land pattern, and use the manufacturer’s application wiring to reduce noise pickup and ensure the remote ground reference is reliable.
推薦
Building Control Networks
The LT3960JMSE#PBF is applicable to building-control equipment that needs to bridge a short I2C controller connection to a more rugged wired node. The CAN-compatible differential receiver supports common-mode conditions of ±25 V or ±36 V depending on VCC, which can improve tolerance to wiring and ground differences compared with an unprotected logic-level link. The device still requires correct supply bypassing, cable routing, and protection planning, and its 400 kbps rate should be checked against the building-system traffic profile.
推薦
Remote Environmental Monitoring
A remote environmental-monitoring station can use the LT3960JMSE#PBF when the sensor controller is more conveniently placed at the edge of a cable run. The transceiver’s 400 kbps I2C communication capability is suitable for periodic sensor reads and control updates, while the physical layer provides a more robust wired connection than an exposed logic bus. Designers should use the two-endpoint arrangement described by Analog Devices and verify EMI, surge, and grounding arrangements for the actual installation.
推薦
Embedded Equipment Communication
The LT3960JMSE#PBF suits embedded equipment that retains an I2C master interface but needs a more resilient physical connection to another module. Its one-driver and one-receiver arrangement is compatible with the two-device extension topology described by Analog Devices. Because the part is a physical-layer transceiver rather than a protocol controller, the host firmware remains responsible for addressing, timing, retries, and bus management. Validate the complete application with the EVAL-LT3960-AZ reference circuit before production release.
推薦
Instrumentation and Test Systems
The LT3960JMSE#PBF can be used in test and measurement equipment where a short internal I2C connection must reach a remote fixture over a longer cable. The CAN-compatible receiver and verified overvoltage-line-fault protection make the physical layer more suitable for a noisy equipment environment than a bare I2C trace, subject to the complete electrical requirements. Keep the transceiver and protection network close to the connector, use a controlled reference ground, and confirm that the 400 kbps target remains adequate for the instrument’s data rate.
推薦
Automotive and Heavy Equipment Links
The LT3960JMSE#PBF may be considered for heavy-equipment communication links where a controller-side I2C connection must cross a noisy harness. Its 400 kbps interface, wide receiver common-mode capability, and overvoltage-line-fault protection are relevant to demanding cable environments, but the supplied data does not confirm AEC-Q100 qualification for this exact suffix. Automotive production use therefore requires separate qualification, environmental testing, and approval under the vehicle program’s specifications.

主要差異化特點
- I2C host-side integration (對比Standard CAN transceivers such as SN75176BD)
- Cable-extension common-mode capability (對比LT3960JMSE#WTRPBF)
- Two-endpoint bus extension (對比LT3960JMSE#WPBF)
- Fault-oriented interface (對比A basic unprotected logic-level transceiver)
設計說明
Use the manufacturer’s 10-pin MSOP exposed-pad footprint and place the transceiver close to the cable-side connector. Keep the logic-side I2C traces short and physically separate from the differential or protected line-side network. Confirm the exposed-pad connection, thermal-via pattern, and pin numbering against the current Analog Devices datasheet before release; the supplied search results confirm the package class but do not reproduce the complete land pattern.
Verify every supply and pin voltage against the official datasheet before connecting external circuitry. The verified material identifies a power-supply range up to 60 V and internal 3.3 V operation, but it does not provide a complete minimum-versus-maximum table for every supply rail. Add the specified bypass capacitors at the device pins, maintain the recommended return-current path, and avoid allowing transients on the cable side to exceed the published limits.
Do not treat the LT3960 as a complete CAN controller. The host must generate the I2C-side activity and manage protocol timing, while the LT3960 provides the physical signaling interface. Also do not infer that a package-identical suffix is automatically a drop-in replacement: verify grade, shutdown behavior, pin functions, temperature range, and qualification in the manufacturer ordering information before substituting an LT3960 variant.
For the two-endpoint extension arrangement, route the line-side connection as a controlled cable interface and keep the connector-side protection network close to the transceiver. Maintain a stable reference ground across the link and use the manufacturer’s recommended topology. The LT3960 receiver’s wide common-mode range improves tolerance to voltage differences, but it does not eliminate the need for shielding, filtering, surge protection, or EMC validation in the final installation.
