Typische Anwendungen
SN65HVD231DR ist geeignet für 6 Anwendungs: Industrial CAN Controller Interface, Automotive Aftermarket CAN Modules, Robotics and Motion-Control Networks, Building and HVAC Network Nodes, Test and Measurement Equipment, Battery-Powered Embedded CAN Nodes.
Industrial CAN Controller Interface
The SN65HVD231DR fits industrial controller nodes that need to connect a 3.3 V CAN controller to a high-speed CAN bus. Its 3 V to 3.6 V supply range matches low-voltage embedded systems, while the 1 Mbps signaling capability supports factory automation, test equipment, and machine-control networks. Place the transceiver between the controller TXD/RXD pins and the differential CANH/CANL bus, then use the manufacturer-recommended supply bypassing and bus termination. The verified ISO 11898-2 compatibility provides a useful baseline, but cable length, node count, common-mode range, and EMC conditions still require system validation.
Empfohlen
Automotive Aftermarket CAN Modules
The SN65HVD231DR can support aftermarket vehicle modules that exchange diagnostic or control data over a 3.3 V CAN bus. Its 1 Mbps maximum rate is suitable for common high-speed CAN networks, and the bus-pin ESD protection exceeding 16 kV HBM is relevant to exposed wiring. However, the exact base-device automotive qualification is not confirmed in the supplied data, so production designs should use the appropriately qualified family member and validate transient immunity, ground offset, bus fault, and sleep-mode requirements. A protective network and chassis-ground strategy should be reviewed with the vehicle electrical architecture.
Empfohlen
Robotics and Motion-Control Networks
The SN65HVD231DR is appropriate for CAN-connected robot controllers, motor-control modules, and distributed actuator nodes. The 3.3 V single-supply operation integrates naturally with compact embedded control systems, and up to 120 supported nodes can simplify larger distributed architectures. CANH and CANL should be routed as a controlled differential pair, with termination placed only at the physical bus ends. The 1 Mbps ceiling is well above common control-message rates, but real-time performance depends on arbitration, bus utilization, cable length, and controller scheduling. Use sleep mode deliberately during idle periods and verify wake-up timing in the complete network.
Empfohlen
Building and HVAC Network Nodes
The SN65HVD231DR can serve as the physical-layer device in building automation, HVAC, and environmental-monitoring nodes using a 3.3 V CAN backbone. The transceiver’s high input impedance supports networks with multiple distributed nodes, while adjustable driver transition times help control signal quality and emissions. A controller must still arbitrate message priority and manage bus-off recovery. For long cables or electrically noisy installations, use a defined topology, proper 120-ohm-style termination where required, common-mode protection, and a ground reference strategy. Verify the complete system against the required EMC and environmental levels rather than relying only on the transceiver datasheet rating.
Empfohlen
Test and Measurement Equipment
The SN65HVD231DR is suitable for CAN-connected test instruments, interface modules, and diagnostic equipment that need reliable high-speed physical-layer signaling. The 3.3 V supply operation simplifies integration with compact embedded controllers, and the verified 1 Mbps rate is suitable for laboratory communication links and multi-node diagnostic fixtures. Keep the CAN bus physically separated from sensitive analog or high-speed digital paths, and use controlled edge rates to reduce radiated emissions. If the test system uses long leads or different ground potentials, add isolation or protection after evaluating loop delay and fault recovery. The exact receive and driver timing should be taken from the official datasheet.
Empfohlen
Battery-Powered Embedded CAN Nodes
The SN65HVD231DR’s sleep-mode architecture is useful for battery-powered embedded nodes that must reduce current when the CAN network is idle. It operates from a single 3.3 V rail and supports high-speed CAN communication up to 1 Mbps when active, allowing the node to combine low-energy operation with deterministic vehicle or industrial communications. The supplied comparison material describes the sleep current as 40 nA, but the test conditions and authoritative manufacturer excerpt were not provided, so that number should not be used as a standalone budget value. Confirm sleep-entry, wake-up, leakage, and bus-recessive behavior with TI before production.

Wichtigste Unterscheidungsmerkmale
- Sleep-mode behavior (vs. SN65HVD230QDRG4)
- High-speed CAN capability (vs. SN65HVD230D)
- Bus scale (vs. TCAN1042H)
- Protection and compatibility (vs. SN65HVD231QD)
Designhinweise
Route CANH and CANL as a closely coupled differential pair with continuous reference-plane support, minimized stubs, and controlled return-current paths. Keep the transceiver close to the CAN connector and away from switching nodes, inductors, and high-current return paths. Use the manufacturer-recommended pin orientation and package footprint, and verify the exact CANH, CANL, TXD, RXD, VCC, and sleep-control pins against the official datasheet before layout release.
Place the transceiver supply bypass capacitor as close as practical to the VCC and ground pins, with a short and low-inductance return path. The verified operating range is 3 V to 3.6 V, so do not expose the device to supply transients or voltages outside the manufacturer absolute-maximum limits. If the CAN bus has chassis wiring or long external leads, evaluate common-mode protection separately rather than assuming the internal ESD rating is a complete surge-protection solution.
Do not confuse standby mode with sleep mode when selecting a substitute. SN65HVD230 is identified as a standby-mode family member, while SN65HVD231 uses sleep mode; replacing one for the other can change firmware control, wake-up timing, and current consumption. Also verify the SOIC-8 pin assignments, termination strategy, bus-fault behavior, and controller logic levels. The verified search results alone do not establish that TCAN1042H is an exact drop-in replacement.
Use adjustable driver transition-time features as part of the overall EMC and signal-quality design. Faster edges improve timing margin but can increase radiated emissions and reflections; slower edges reduce emissions but may reduce available timing margin at the selected bit rate. Validate CAN waveform quality, reflections, bus-fault recovery, and emissions with the intended cable length, topology, termination, and connector in the final system.
CAN transceiver dissipation is generally modest compared with power converters, but exposed bus faults, excessive load, or repeated fault recovery can increase current. Estimate worst-case dissipation using the actual supply voltage and enabled-state current, then compare junction temperature with the package and board thermal limits. The verified excerpts do not provide the required thermal-resistance values, so obtain them from the manufacturer datasheet before conducting a production thermal calculation.
Compliance-Informationen
The supplied verified data confirms ISO 11898-2 compatibility and bus-pin ESD protection exceeding 16 kV HBM, but does not provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations for the exact SN65HVD231DR orderable part.
