Part Audit Review
Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.
Thought for 10 sec
I’ll audit the part metadata, source the official TI datasheet if needed, verify symbol/footprint/pin descriptions, and correct the Datasheet property before reporting any mismatches.

TCAN1462VDRQ1 Part Audit
Official TI datasheet: https://www.ti.com/lit/ds/symlink/tcan1462-q1.pdf Existing Datasheet URL property: https://www.ti.com/general/docs/su...
Audit complete. The existing Datasheet URL already points to TI’s official datasheet, and the SOIC-8 footprint closely matches TI’s land pattern; key mismatches are pin 5 labeled
NC_VIO instead of VIO, unspecified pin types/descriptions, missing explicit package metadata, and an incorrect Logic Function = AND.Full findings: TCAN1462VDRQ1 Part Audit

- Official TI datasheet: https://www.ti.com/lit/ds/symlink/tcan1462-q1.pdf
- Existing Datasheet URL property:
https://www.ti.com/general/docs/suppproductinfo.tsp?distId=26&gotoUrl=https://www.ti.com/lit/gpn/tcan1462-q1 - TI orderable device: TCAN1462VDRQ1
The existing Datasheet URL is already populated and resolves to TI's official datasheet, so no property update was required.
Current part metadata
- MPN: TCAN1462VDRQ1 — correct
- Manufacturer: Texas Instruments — correct
- Description:
CAN Interface IC Automotive signal improvement CAN FD transceiver with VIO and standby— functionally correct, though terse - Pin count: 8 — correct
- Part Type: Integrated Circuits — acceptable but broad
- Part subtype: Logic — overly broad/inaccurate; this is a CAN physical-layer transceiver/interface IC
- Logic Function: AND — incorrect and unrelated to this device
- Package property: no explicit Package or Case Code was found in the available properties; it should identify SOIC (D), 8-pin / D0008A

|---|---|---|---|---|
| 1 | TXD | Digital input; CAN transmit data; internal pull-up | TXD | Name/number correct; Pin Type and Pin Description missing |
| 2 | GND | Ground | GND | Name/number correct; Pin Type and Pin Description missing |
| 3 | VCC | 5 V supply | VCC | Name/number correct; Pin Type and Pin Description missing |
| 4 | RXD | Digital output; tristate when powered off | RXD | Name/number correct; Pin Type and Pin Description missing |
| 5 | VIO | Logic I/O supply on the V variant | NC_VIO | Mismatch: exact MPN requires VIO, not NC/ambiguous naming; Pin Type and description missing |
| 6 | CANL | CAN bus low bidirectional I/O | CANL | Name/number correct; Pin Type and Pin Description missing |
| 7 | CANH | CAN bus high bidirectional I/O | CANH | Name/number correct; Pin Type and Pin Description missing |
| 8 | STB | Standby control digital input; internal pull-up | STB | Name/number correct; Pin Type and Pin Description missing |
All terminal
Pin Type values are currently Unspecified. No datasheet-derived Pin Description properties were found.Symbol review
- Pin numbering and top-view left/right ordering match the SOIC-8 datasheet pinout.
- The main symbol defect is pin 5 labeled NC_VIO. For TCAN1462VDRQ1, pin 5 must be unambiguously VIO.
- Electrical pin types should be assigned: TXD/STB = digital inputs, RXD = digital output, VCC/VIO = supply, GND = ground, CANH/CANL = bidirectional bus I/O.
Footprint review
The footprint is an 8-pad SOIC pattern with:
- 1.27 mm pad pitch
- Approximately 5.422 mm row-to-row pad-center spacing
- Pad size approximately 0.65 mm x 1.528 mm
TI's example land pattern specifies:
- 1.27 mm pitch
- 5.4 mm row-to-row pad-center spacing
- 0.6 mm x 1.55 mm pads
The implemented pattern is very close to TI's recommended land pattern and is consistent with SOIC-8 D0008A. Differences are minor: pads are about 0.05 mm wider and 0.022 mm shorter, with row spacing about 0.022 mm larger. No missing or extra pads were found.
Flagged mismatches and recommended corrections
- High priority: Rename pin 5 from
NC_VIOtoVIOfor this exact V-suffix MPN. - High priority: Replace the erroneous
Logic Function = ANDmetadata. - Medium priority: Add explicit package metadata:
SOIC (D), 8-pin/D0008A. - Medium priority: Set all pin electrical types and add datasheet-derived pin descriptions.
- Low priority: Change subtype/classification from generic
Logicto a CAN transceiver/interface classification if supported. - Low priority: The footprint dimensions are acceptable and closely match TI's example; standardizing exactly to 0.6 mm x 1.55 mm and 5.4 mm row spacing is optional unless strict datasheet fidelity is required.
