SN65HVD251QDRQ1

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.
