Texas Instruments · CAN Transceivers · SOIC-8
SN65HVD251QDRQ1 from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | D | input | Driver input; low drives the bus dominant, high or open leaves it recessive, with input range -0.3 V to VCC + 0.5 V. |
| 2 | GND | power_in | Ground (network ground reference). |
| 3 | VCC | power_in | Supply voltage, 4.5 V to 5.5 V recommended (absolute maximum 7 V). |
| 4 | R | output | Receiver output, low when VID >= 0.9 V and high when VID <= 0.5 V or the bus is open. |
| 5 | Vref | power_in | Reference output voltage of 0.45 VCC to 0.55 VCC for -5 uA < IO < 5 uA. |
| 6 | CANL | bidirectional | Low-level CAN bus line, with bus-fault protection of -36 V to 36 V. |
| 7 | CANH | bidirectional | High-level CAN bus line, with bus-fault protection of -36 V to 36 V. |
| 8 | Rs | input | Mode select: ground gives high-speed mode, a resistor to ground (0 to 100 kOhm) sets slope control, and a high level (above 0.75 VCC) gives standby. |
