Symbol pin placement is functional rather than package-top-view. Inputs are on the left and output/power/NC pins are distributed around the symbol. Electrical pin-number mapping is correct.
7.81 mm nominal row spacing from pad X positions ±3.905 mm
Pad 1 is rectangular; other pads are circular
Pad numbering follows standard DIP pattern: left side pins 1-4, right side pins 5-8
Courtyard approximately 9.914 mm × 10.66 mm
Fabric body approximately 7.112 mm × 10.16 mm
Datasheet package notes for 8-lead PDIP:
8 leads
0.100 in / 2.54 mm pitch
300 mil class body; shoulder-to-shoulder width nominal 0.310 in / 7.87 mm
Molded body length nominal 0.365 in / 9.27 mm, max 0.400 in / 10.16 mm
Footprint result: pin count, through-hole DIP style, 2.54 mm pitch, row spacing, and numbering are consistent with the MCP6541-I/P 8-PDIP package. No footprint mismatch found from the available data.
Mismatches / issues flagged
Pin description properties are missing. All terminal components show Pin Type: Unspecified and no Pin Description values. This is not an electrical pinout error, but the part metadata is incomplete compared with the datasheet.
Terminal naming differs slightly from datasheet. Pin 3 is named VINA+; the datasheet name is VIN+. The function and pin number are correct, but the label is not an exact datasheet match.
Datasheet URL property is not the official Microchip URL. A Datasheet URL is present, but it points to a stored uploaded PDF. The official Microchip URL found during review is listed above.
Overall conclusion
The MCP6541-I/P part is broadly correct: MPN, manufacturer, package, pin count, symbol pin-number mapping, and footprint all match the Microchip datasheet. The main improvements are metadata cleanup: add pin descriptions/types, optionally rename VINA+ to VIN+, and consider replacing the uploaded Datasheet URL with the official Microchip datasheet URL.
