# TCAN330DR

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

TCAN330DR 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 drives the bus dominant and HIGH releases it to recessive, with an integrated pull-up. |
| 2 | GND | power_in | Ground connection; all voltages are referenced to this terminal. |
| 3 | VCC | power_in | 3.3-V supply voltage; recommended operating range is 3 V to 3.6 V, and the absolute maximum is 5 V. |
| 4 | RXD | tri_state | CAN receive data output: LOW for dominant and HIGH for recessive bus states; it is tri-stated (high impedance) during an undervoltage or unpowered condition. |
| 5 | SHDN | input | Drive high to enter shutdown mode; the internal pull-down weakly biases the pin toward normal mode and should not be relied on by design. |
| 6 | CANL | bidirectional | Low-level CAN bus line; bus terminals tolerate -14 V to 14 V and have ±25 kV HBM ESD protection. |
| 7 | CANH | bidirectional | High-level CAN bus line; bus terminals tolerate -14 V to 14 V and have ±25 kV HBM ESD protection. |
| 8 | S | input | Drive high to enter silent mode; the integrated pull-down weakly biases the pin toward normal mode and should not be relied on by design. |

## CAD (KiCad official)

- Symbol: `TCAN330DR`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `tcan330dr-etched.step` / `tcan330dr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tcan330dr.step` / `tcan330dr.glb` are the bare package body.
