# TCAN1042VDRBTQ1

**Texas Instruments** · CAN Transceivers · HVSON-8-EP(3x3)

TCAN1042VDRBTQ1 from Texas Instruments, in a HVSON-8-EP(3x3). 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 for dominant and HIGH for recessive bus states. |
| 2 | GND | power_in | Ground connection; for the DRB (VSON) package the thermal pad may be connected to GND to optimize thermal characteristics. |
| 3 | VCC | power_in | Transceiver 5-V supply voltage. |
| 4 | RXD | output | CAN receive data output: LOW for dominant and HIGH for recessive bus states. |
| 5 | VIO | power_in | Transceiver I/O level-shifting supply voltage; pin 5 is VIO only on devices with the V suffix, which includes TCAN1042VDRBTQ1. |
| 6 | CANL | bidirectional | Low-level CAN bus input/output line. |
| 7 | CANH | bidirectional | High-level CAN bus input/output line. |
| 8 | STB | input | Standby Mode control input, active high. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

## CAD (KiCad official)

- Symbol: `TCAN1042VDRBTQ1`
- Footprint: `Package_SON:HVSON-8-1EP_3x3mm_P0.65mm_EP1.6x2.4mm`
- 3D model: HVSON-8-EP(3x3), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.9 mm nominal VQFN height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `tcan1042vdrbtq1-etched.step` / `tcan1042vdrbtq1-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tcan1042vdrbtq1.step` / `tcan1042vdrbtq1.glb` are the bare package body.
