# TCAN1051HDRQ1

**Texas Instruments** · CAN Transceivers · SOIC-8

TCAN1051HDRQ1 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 | TXD | input | CAN transmit data input; LOW gives a dominant bus state and HIGH gives a recessive bus state. |
| 2 | GND | power_in | Ground connection for the transceiver. |
| 3 | VCC | power_in | Transceiver 5-V supply voltage input. |
| 4 | RXD | output | CAN receive data output; LOW indicates a dominant bus state and HIGH indicates a recessive bus state. |
| 5 | NC | unconnected | No connect on the (H) variant; the pin is not internally connected and can be left floating or tied to any existing net. |
| 6 | CANL | bidirectional | Low-level CAN bus input/output line. |
| 7 | CANH | bidirectional | High-level CAN bus input/output line. |
| 8 | S | input | Silent mode control input, active high. |
