Received notification from "TCAN1462VDRQ1 Pin Fix" that it finished — picking the work back up.

I’ve reconciled the executor’s result: the pin metadata correction is complete and footprint mapping is preserved. I’m checking for an available publication path before closing, since the executor reported publishing was unavailable.

flux

The new library version is published. I’m completing the final read-back using the current project state because the published library version ID is separate from the project-history commit ID.

Updated and published TCAN1462VDRQ1 pin 5:
  • Name: VIO
  • Pin number: 5
  • Type: Power In
  • Description: Logic supply voltage; I/O level-shifting supply input, 1.8 V to 5.5 V.
Verified all 8 terminals remain unique, VIO maps to footprint pad 5, and the unchanged footprint is SOIC127P600X175-8N.kicad_mod. No terminal or footprint check failures were reported.

TCAN1462VDRQ1 Part Audit
Sources
  • 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
Datasheet key specifications
  • Automotive CAN/CAN FD physical-layer transceiver with TX-based Signal Improvement Capability (SIC)
  • Meets ISO 11898-2:2016 and CiA 601-4
  • Classical CAN and CAN FD operation up to 8 Mbps
  • VCC recommended range: 4.5 V to 5.5 V, nominal 5 V
  • VIO recommended range: 1.7 V to 5.5 V, supporting 1.8 V, 2.5 V, 3.3 V, and 5 V controllers
  • CANH/CANL bus fault protection: -58 V to +58 V absolute maximum
  • Recommended junction temperature: -40°C to +150°C
  • Orderable-device operating temperature listing: -40°C to +125°C
  • Standby mode with remote wake-up; TXD and STB include internal pull-ups
  • SOIC package: TI D, 8 pins, nominal body/package envelope about 4.9 mm x 6 mm, 1.27 mm lead pitch

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.
  1. High priority: Rename pin 5 from NC_VIO to VIO for this exact V-suffix MPN.
  2. High priority: Replace the erroneous Logic Function = AND metadata.
  3. Medium priority: Add explicit package metadata: SOIC (D), 8-pin / D0008A.
  4. Medium priority: Set all pin electrical types and add datasheet-derived pin descriptions.
  5. Low priority: Change subtype/classification from generic Logic to a CAN transceiver/interface classification if supported.
  6. 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.
