Part Audit Review
Thought for 10 sec
Yes. I’ll group every pin once by its primary function—Power, Ground, Inputs, and Outputs—without duplicates, and keep each pin’s Section matched to its Pin Group while completing the datasheet audit.
Worked for 4 mins 18 sec
The metadata and pin grouping are updated. I’m doing a final read-back of all 14 terminals and checking the official TI package/pin data before closing the audit.

Created a project doc
Completed the full audit and grouped every pin exactly once: Inputs, Outputs, Power, and Ground. Pin mapping and the TSSOP-14 footprint match TI documentation; the incorrect wettable-flank claim was removed.
- The existing datasheet field already contained a valid mirrored PDF, so it was not replaced; the canonical TI URL is recorded.
- The terminal metadata is correct, but the generated symbol still has a visual rendering/asset issue that should be checked before publishing.

Pin verification and grouping
Table
| Pin | Name | Type | Primary group | Description |
|---|---|---|---|---|
| 1 | 1A | Input | Inputs | Channel 1 Schmitt-trigger input A |
| 2 | 1Y | Output | Outputs | Channel 1 inverted output Y |
| 3 | 2A | Input | Inputs | Channel 2 Schmitt-trigger input A |
| 4 | 2Y | Output | Outputs | Channel 2 inverted output Y |
| 5 | 3A | Input | Inputs | Channel 3 Schmitt-trigger input A |
| 6 | 3Y | Output | Outputs | Channel 3 inverted output Y |
| 7 | GND | Ground | Ground | Ground reference |
| 8 | 4Y | Output | Outputs | Channel 4 inverted output Y |
| 9 | 4A | Input | Inputs | Channel 4 Schmitt-trigger input A |
| 10 | 5Y | Output | Outputs | Channel 5 inverted output Y |
| 11 | 5A | Input | Inputs | Channel 5 Schmitt-trigger input A |
| 12 | 6Y | Output | Outputs | Channel 6 inverted output Y |
| 13 | 6A | Input | Inputs | Channel 6 Schmitt-trigger input A |
| 14 | VCC | Power In | Power | Positive supply voltage |
Every physical pin is assigned to exactly one primary group. Section matches Pin Group for all terminals. Inputs are oriented Left with orders 1-6; Outputs are oriented Right with orders 1-6; VCC is Power/Top/order 1; GND is Ground/Bottom/order 10.
Footprint cross-check
- 14 surface-mount pads: correct
- Pad pitch: 0.65 mm, correct
- Current pad size: 0.45 mm x 1.475 mm, effectively consistent with TI's approximately 0.45 mm x 1.5 mm land recommendation
- Current row span: approximately 5.876 mm, consistent with the TI recommended land-pattern span near 5.8 mm
- PW0014A package body: 5.0 mm x 4.4 mm nominal, 1.2 mm maximum height
- Pin-1 silk indicator is present
Corrections and mismatches
- Corrected the description/package metadata to standard PW TSSOP-14.
- Removed the implication that the PWRQ1 ordering code itself uses wettable flanks. TI offers wettable flanks on the separate BQA/WQFN package; PW is the TSSOP option.
- Added Pin Description, Pin Type, Pin Group, Section, Pin Orientation, and Terminal Order to all terminals.
- The stored Datasheet URL was already populated with a mirrored copy, so the conditional request to add a URL was not triggered. The canonical TI URL is recorded above; an attempted replacement did not persist through the available metadata interface.
- Terminal metadata reads back correctly, but the generated symbol has shown a renderer/asset presentation issue. This does not indicate a pin-number or footprint-mapping mismatch, but visual symbol rendering should be rechecked before publishing.
- A generic project DRC error was reported without accessible item-level detail; it was not identified as a footprint geometry error.
