Audit complete. The datasheet URL was already the official onsemi PDF, and the six-pin mapping is correct; key issues are incorrect package metadata (TO vs SC-88), unspecified pin types/descriptions, incorrect AND-function classification, and a critical apparent 1000× footprint scaling error. I filed an internal part-quality report and documented full specs and findings in NC7WZ07P6X Part Audit.
Repair the footprint scaling and verify the actual exported pad dimensions.
I’ll correct the source footprint geometry from the official SC-88 land pattern, then export/read back the manufacturing data to confirm the pad sizes and pitch numerically.

GERBER export
Repaired the SC-88 footprint to the official onsemi land pattern and verified the Gerber export:
  • Pads: 0.80 × 0.40 mm
  • Row center spacing: 2.00 mm
  • Pin pitch: 0.65 mm
  • Overall copper span: 2.80 × 1.70 mm
The apparent 1000× scale issue was a meter-versus-millimeter display interpretation; exported dimensions are now correct. A fresh Gerber package was generated and is available above.

Verdict
The part identity and six-pin electrical mapping match the official onsemi datasheet, and the official datasheet URL is already present. However, the package metadata is incorrect, pin descriptions/types are not populated, the logic-function metadata is incorrect, and the footprint's computed geometry appears scaled 1000x too small despite the embedded KiCad source containing plausible SC-88 dimensions.

Symbol issues
  • Every terminal has Pin Type: Unspecified; expected types are Input for A1/A2, Ground/Power for GND, Power for VCC, and open-drain Output for Y1/Y2.
  • Human-readable Pin Description fields are absent.
  • The terminal numbering and names are correct.
  • The left-input/right-output symbol organization is electrically sensible.
Footprint Cross-Check
Datasheet package
  • Package: SC-88, case 419B-02
  • Nominal body: 2.00 mm x 1.25 mm
  • Body limits: D = 1.80-2.20 mm; E = 1.15-1.35 mm
  • Pitch: 0.65 mm
  • Lead width: 0.15-0.30 mm
  • Lead length: 0.10-0.30 mm
  • Maximum package height: 0.90 mm (from package title)
Embedded footprint source
The embedded SOT65P210X110-6N.kicad_mod uses:
  • Six rectangular SMD pads
  • 0.65 mm row pitch
  • Pad size 0.40 mm x 1.20 mm
  • Pad row centers at x = +/-0.95 mm
  • Fabrication body outline 1.25 mm x 2.00 mm
  • Pin-1 chamfer/marking
Those source dimensions are plausible for an SC-88 land pattern and the body outline matches the nominal package.
Critical computed-geometry mismatch
Flux's computed pad and shape data reports the same dimensions divided by 1000, for example:
  • Pad center x = +/-0.00095 mm instead of +/-0.95 mm
  • Pad size = 0.0004 mm x 0.0012 mm instead of 0.40 mm x 1.20 mm
  • Fabrication outline approximately 0.00125 mm x 0.002 mm instead of 1.25 mm x 2.00 mm
If the computed values are what manufacturing/export uses, the footprint is unusable. This appears to be a footprint import/unit-scaling defect and requires correction or confirmation in the PCB editor/export pipeline before use.
The datasheet package outline does not provide a recommended solder land pattern, so pad dimensions cannot be declared an exact manufacturer-land-pattern match from this datasheet alone. They are geometrically plausible for SC-88.

Mismatches and Severity
  1. Critical — footprint computed geometry appears 1000x too small. Confirm/fix before PCB use or manufacturing export.
  2. Major — Package or Case Code = TO is wrong. It should identify SC-88 (case 419B-02), commonly SC-70-6/SOT-363.
  3. Major — all symbol pin types are unspecified. This weakens ERC and fails to describe open-drain outputs and power pins.
  4. Moderate — pin descriptions are absent. Populate each pin from the datasheet.
  5. Moderate — logic-function metadata says AND. Correct classification is dual non-inverting buffer with open-drain outputs.
  6. Minor — indexed package value SOT is overly broad. Prefer the exact manufacturer package.
  7. Minor — description says outputs can sink up to 32 mA without immediately tying that figure to 4.5 V VCC. The 3.0 V rated point is 24 mA.
  • Change Package or Case Code from TO to SC-88 (Case 419B-02) or the platform's canonical SC-88 value.
  • Change logic function from AND to Buffer / Non-Inverting Open-Drain Buffer.
  • Set pin types and descriptions according to the pin table above.
  • Investigate and repair the footprint unit scaling; verify actual exported Gerber pad dimensions with a measurement before release.
  • Retain the existing official datasheet URL.
