Features

  • Single 3.3V supply operation
  • ISO 11898-2 compliant CAN transceiver
  • Low-power replacement for PCA82C250
  • Bus pin ESD protection exceeding ±16 kV HBM
  • High input impedance allows up to 120 nodes on a bus
  • Adjustable driver transition times for improved EMC
  • Three operating modes: high-speed, slope control, standby
  • Thermal shutdown and open-circuit fail-safe

Applications

  • Industrial automation and control
  • Motor and robotic control
  • Building and HVAC automation
  • Automotive CAN networks
  • CANopen, DeviceNet, CAN Kingdom

The SN65HVD230DR from Texas Instruments is a 3.3V CAN bus transceiver compatible with the ISO 11898-2 standard for high-speed CAN physical layer. It is designed for data rates up to 1 Mbps and includes multiple protection features for robust operation in harsh environments. The RS pin provides three operating modes: high-speed, slope control, and low-power standby, allowing flexible system design. The device is pin-compatible with the PCA82C250 as a low-power alternative.

The SN65HVD230DR interfaces a single-ended CAN protocol controller to the differential CAN bus. The driver converts single-ended TX data to differential signals on CANH and CANL, while the receiver converts the differential bus signal back to single-ended RX data. The RS pin controls the operating mode: grounded for high-speed mode (unlimited slew rate), connected through a resistor for slope control (proportional to current), or pulled high for standby mode where the driver is disabled but the receiver remains active. Thermal shutdown protects against overtemperature conditions, and the open-circuit fail-safe design ensures defined states on unterminated buses.

Pin Name Type Function
1 D Input CAN transmit data input from controller
2 GND Ground Ground reference
3 VCC Power 3.3V supply voltage
4 R Output CAN receive data output to controller
5 Vref Output Reference voltage output (VCC/2)
6 CANL I/O CAN bus low-side line
7 CANH I/O CAN bus high-side line
8 RS Input Mode select (high-speed / slope / standby)
  • Industrial automation with CAN bus
  • Motor control and robotics
  • Building climate control (HVAC)
  • Automotive CAN networks and gateways
  • CANopen and DeviceNet systems
