SN65HVD1040DR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | TXD | input | CAN transmit data input from the CAN controller. LOW drives the bus to the dominant state; HIGH allows the bus to go to the recessive state. Input voltage range 0 to 5.25 V (VIH ≥ 2 V, VIL ≤ 0.8 V). |
| 2 | GND | power_in | Device ground reference. |
| 3 | VCC | power_in | Transceiver 5-V supply. Recommended operating range 4.75 V to 5.25 V. Decouple to GND close to the pin. |
| 4 | RXD | output | CAN receive data output to the CAN controller. LOW indicates dominant bus state; HIGH indicates recessive bus state. IOH = -2 mA, IOL = 2 mA. |
| 5 | SPLIT | output | Reference output voltage (VCC/2) intended to bias the common-mode of a split-termination network on the CAN bus for improved EMC. |
| 6 | CANL | bidirectional | Low-level CAN bus line. Differential I/O with CANH; withstands -27 V to 40 V bus faults and ±200 V transients per ISO 7637. Common-mode range -12 V to 12 V. |
| 7 | CANH | bidirectional | High-level CAN bus line. Differential I/O with CANL; withstands -27 V to 40 V bus faults and ±200 V transients per ISO 7637. Common-mode range -12 V to 12 V. |
| 8 | STB | input | Mode select input. Strong pulldown to GND selects high-speed mode; strong pullup to VCC selects low-power standby (bus-monitor) mode. VIH ≥ 2 V, VIL ≤ 0.8 V. |
