SN65HVD71D

SN65HVD71D is Texas Instruments’ high‑speed CAN transceiver. It sits between a CAN controller (MCU) and the CAN bus, handling the physical layer: it converts TXD/RXD to differential CANH/CANL on the bus and back. Key points:
- Supports CAN 2.0A/2.0B at up to 1 Mbps.
- Supply voltage: typically 4.5–5.5 V.
- Built‑in protections: short‑circuit protection on CANH/CANL, undervoltage, over‑temperature, and ESD protection.
- Low‑power features: sleep/standby mode to reduce idle current.
- Wide bus common‑mode range for automotive/industrial wiring.
- Common applications: automotive ECUs and industrial CAN networks.
- Package: -D suffix indicates a surface‑mount package (e.g., SOIC‑8).

- ROHM BM1S CAN transceiver family
Note: pinout, voltage ranges and automotive vs. industrial grades vary. Use a cross-ref tool to confirm a direct drop-in substitute.

Here are the key features of SN65HVD71D (high‑speed CAN transceiver):
- CAN transceiver for CAN 2.0B with data rate up to 1 Mbps
- ISO 11898-2 compliant differential CANH/CANL interface
- Robust protection: bus fault protection on CANH/CANL; short-to-GND and short-to-VCC protection; undervoltage/overcurrent protection; thermal shutdown
- ESD protection on I/O and bus pins
- Slew-rate controlled outputs to reduce EMI (slower edge rate)
- Fail-safe recessive state on fault, open bus, or power-down
- Sleep/low-power mode with wake-up capability
- TXD input and RXD output interface compatible with standard microcontrollers
- Suitable for automotive/industrial environments with wide operating range
Note: For exact electrical specs (voltages, protections, and timing), refer to the TI datasheet.

- Pin count: 8 pins (SOIC-8/TSSOP-8 package).
- Function: Single‑channel CAN transceiver. It interfaces a CAN controller to the CAN bus by:
- Driving CANH/CANL from TXD (logic side) to the bus (bus side)
- Presenting RXD (to the controller) from CANH/CANL
- Providing power (VCC) and ground (GND)
- Including a standby/enable control (e.g., STB or EN) for low‑power operation
- The remaining pins are typically used for VCC/GND, and may include a VREF/NC depending on package variant; exact pinout varies by package and should be checked in the datasheet.

- Manufacturer: Texas Instruments (TI).
- What kind of company: TI is an American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits.

SN65HVD71D is a high-speed CAN transceiver. Typical application areas include:
- Automotive in-vehicle networks (ECUs, engine, body/chassis) requiring robust CAN signaling
- Industrial automation and control (CANopen, J1939), motor drives, robotics
- Data acquisition and instrumentation systems that use CAN buses
- Any 5-V CAN system needing reliable, high-speed differential signaling and fault protection
Note: suited for environments requiring durable CAN performance with protection against transients.

SN65HVD71D is available in an 8‑pin SOIC (D‑package).
