HX65HVD251-S from ZHHXDZ, in a SOP-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 | Transmit data input; has a pull-up to VCC so the bus stays recessive when unpowered, with a dominant time-out timer, VIH min 2 V and VIL max 0.8 V. |
| 2 | GND | power_in | Ground supply. |
| 3 | VCC | power_in | Supply voltage, VCC=5V±10%. |
| 4 | R | output | Receive data output that reads out data from the bus lines; VOH min 4 V at IO=-2 mA and VOL max 0.4 V at 2 mA. |
| 5 | Vref | power_in | Common-mode stabilization output, 0.3VCC to 0.7VCC for load currents between -500 µA and 500 µA. |
| 6 | CANL | bidirectional | LOW-level CAN bus line, with bus-side voltage rating of -60 V to +60 V. |
| 7 | CANH | bidirectional | HIGH-level CAN bus line, with bus-side voltage rating of -60 V to +60 V. |
| 8 | Rs | input | High speed and standby mode selection; low (grounded) selects high speed, high or unconnected selects standby mode. |
