Part Review Audit
Worked for 3 mins 7 sec
Created a project doc
Completed the part review and created the detailed report: TCAN3414DRBR Part Review. The pin numbers match the TI datasheet, but I flagged metadata issues: datasheet URL inconsistency, V_CC naming vs VCC, missing pin descriptions/types, EP needing clearer thermal/ground description, and footprint land-pattern dimensions larger than TI’s example.
Open items:
- Datasheet URL is already set, so I did not overwrite it; official TI URL found:
https://www.ti.com/lit/gpn/tcan3414 - Footprint should be DFM-checked against your assembler’s rules.
Suggested next steps:
- Update the Datasheet URL to the official TI link.
- Populate pin descriptions and pin types.
- Rename
V_CCtoVCCif you want exact datasheet naming. - Review the DRB footprint pad sizes and exposed-pad paste strategy.
Apply fixes and verify
Update metadata
Rename VCC pin
Review footprint DFM
Fix classification
Run review checks

Pinout cross-check
TI DRB VSON-8 top-view pinout:
Table
| Pin | Datasheet name | Datasheet type / function | Flux terminal | Result |
|---|---|---|---|---|
| 1 | TXD | Digital input; CAN transmit data input; integrated pull-up | TXD | Match |
| 2 | GND | Ground | GND | Match |
| 3 | VCC | 3.3-V supply | V_CC | Electrically matches; naming differs from datasheet |
| 4 | RXD | Digital output; CAN receive data output; tri-stated when unpowered | RXD | Match |
| 5 | SHDN | Digital input; shutdown high; integrated pull-down; TCAN3414 only | SHDN | Match |
| 6 | CANL | CAN low bus I/O | CANL | Match |
| 7 | CANH | CAN high bus I/O | CANH | Match |
| 8 | STB | Digital input; standby mode control; integrated pull-up | STB | Match |

Symbol cross-check
- Pin numbers in Flux match the TCAN3414DRBR datasheet pinout.
- Symbol arrangement is logical: TXD/GND/V_CC/RXD on left, SHDN/CANL/CANH/STB on right, EP separated at bottom.
- The VCC terminal is named V_CC rather than VCC. This is acceptable electrically but differs from the datasheet and may be less discoverable in search/autowiring.
- All terminal Pin Type properties inspected are currently "Unspecified".
- Pin Description properties were not present in the inspected terminal properties.
Footprint / package cross-check
Datasheet/orderable package information:
- Orderable part: TCAN3414DRBR
- Package: SON / VSON, TI package code DRB, 8 pins plus exposed thermal pad
- Drawing: DRB0008B, VSON - 1 mm max height, nominal 3 mm × 3 mm body
- Pitch: 0.65 mm
- Package lead size: 0.25-0.35 mm × 0.3-0.5 mm
- Exposed thermal pad: 1.65 ±0.05 mm × 2.4 ±0.05 mm
- Example board layout: side pads 0.3 mm × 0.6 mm; 0.65 mm pitch; exposed pad 1.65 mm × 2.4 mm; optional thermal vias.
Flux footprint observed:
- Footprint asset: SON65P300X300X100-9N-D.kicad_mod
- Footprint description: DRB0008B
- Pads 1-8: rectangular SMD pads at ±1.45 mm X, 0.65 mm pitch in Y, pad size 0.35 mm × 0.85 mm, rotated 90°
- Exposed pad 9: rectangular SMD pad 1.7 mm × 2.45 mm
- Fab outline: 3.0 mm × 3.0 mm with pin-1 chamfer
- Courtyard: 4.25 mm × 3.6 mm
- 3D model asset: TCAN3414DRBR.stp
Footprint assessment:
- Package identity, 8 pins plus exposed pad, pitch, body outline, and thermal pad are consistent with DRB0008B.
- The exposed pad is 1.70 mm × 2.45 mm, which is 0.05 mm larger than the TI nominal exposed pad / example land size of 1.65 mm × 2.40 mm. This may be an intentional land-pattern expansion but should be checked against TI land-pattern guidance and assembly-house rules.
- Side pads are 0.35 mm × 0.85 mm versus TI example board-layout land pads of about 0.30 mm × 0.60 mm. This is larger than the TI example; it may still be manufacturable but should be validated for solder bridging/paste aperture with the selected assembler.
- No thermal vias or stencil paste window segmentation were observed in the Flux footprint. The datasheet says the thermal pad must be soldered to the PCB; vias are optional depending on application, and paste coverage guidance is provided.
Mismatches / issues flagged
- Datasheet URL consistency: project has an uploaded PDF URL; library search result shows a TI TCAN3413 symlink; official TCAN3414-specific URL is https://www.ti.com/lit/gpn/tcan3414. The current project URL is set, so no automatic update was required, but the official TI URL is preferable.
- Terminal naming: pin 3 is V_CC in Flux, while the datasheet name is VCC. This is a minor naming mismatch.
- Pin metadata incomplete: all inspected terminal Pin Type values are Unspecified, and Pin Description properties are missing. Recommended types/descriptions should be populated from the datasheet.
- EP metadata incomplete: exposed pad is present as pin 9/EP but should be clearly described as thermal pad / ground connection and ideally grouped/typed as Ground or Power/Thermal per library conventions.
- Footprint land pattern dimensions differ from TI example: side pads and exposed pad are larger than TI example dimensions. This is not necessarily wrong, but it is a manufacturability item to verify.
- Part type-specific library values appear generic/inaccurate: library search reports part_sub_type Logic and logicFunction AND, which does not describe a CAN FD transceiver.
Recommended corrections
- Change Datasheet URL to the official TI TCAN3414 URL: https://www.ti.com/lit/gpn/tcan3414
- Consider renaming V_CC to VCC for datasheet consistency.
- Add pin descriptions and pin types:
- TXD: Digital Input; CAN transmit data input; integrated pull-up
- GND: Ground
- VCC: Supply; 3.3-V supply voltage
- RXD: Digital Output; CAN receive data output; tri-stated when unpowered
- SHDN: Digital Input; shutdown high; integrated pull-down; TCAN3414 only
- CANL: Bus I/O; CAN low bus line
- CANH: Bus I/O; CAN high bus line
- STB: Digital Input; standby mode control; integrated pull-up
- EP: Thermal/Ground pad; connect to PCB ground plane with multiple vias where needed
- Review/update part classification from generic logic/AND to CAN/CAN FD transceiver / interface IC if those properties are editable.
- Validate the footprint land pattern against TI DRB0008B guidance and assembler DFM rules, especially paste/stencil design for the exposed pad.
