Part Review and Datasheet Update

Completed the review and attached the official Renesas DG401/DG403 datasheet URL to the part project. I found a major issue: the current symbol/footprint pin mapping does not match the Renesas DG403DYZ datasheet — only VL on pin 12 matches; 15 of 16 pins are mismatched.
Full findings, key specs, and the pin-by-pin mismatch table are saved in DG403DYZ-ND Part Review (dg403dyz-nd-part-review). Recommended next step is to correct the symbol pin names/numbers and change Manufacturer Part Number from Digi-Key DG403DYZ-ND to manufacturer MPN DG403DYZ.
Please correct the symbol pin names and numbers to match the Renesas DG403DYZ datasheet.
I’ll update the terminal names and Pin Number properties to match the Renesas DG403DYZ 16-pin datasheet pinout, then re-read the symbol to verify the mapping.
Updated the DG403DYZ symbol terminals to match the Renesas datasheet pinout: pin 1 IN1, 2 D1, 3 S1, 4 V-, 5 GND, 6 S4, 7 D4, 8 IN4, 9 IN3, 10 D3, 11 S3, 12 VL, 13 V+, 14 S2, 15 D2, 16 IN2.
I verified the schematic now has all 16 expected terminal names and pin numbers. Note: one terminal (D4) had to be replaced rather than renamed because the duplicate NC label would not target reliably by UID; its Pin Number and symbol pin position were restored.

Findings
  1. Major symbol/footprint pin-number mismatch: 15 of 16 pins do not match the Renesas DG403 datasheet pinout. Only pin 12 (VL) is correct.
  2. Missing control pins: current symbol has two NC pins at pins 2 and 7, but the datasheet pinout requires D1 and D4 at those positions. The actual DG403 control pins IN3 and IN4 are also absent from the current naming scheme, while the symbol only exposes IN1 and IN2.
  3. Power pins are assigned to the wrong physical pads: datasheet expects pin 4 = V−, pin 5 = GND, pin 12 = VL, pin 13 = V+; current symbol has V− at pin 14, GND at pin 13, V+ at pin 11, and VL correctly at pin 12.
  4. Footprint family appears plausible: SOIC16_4X10_INR with 16 pads and 1.27 mm pitch is consistent with a 16-lead SOIC-style package. Mechanical dimensions should still be checked against the exact Renesas DYZ package drawing before release, but the critical issue is pin mapping rather than pad count.
  5. MPN property concern: the current Manufacturer Part Number is DG403DYZ-ND, which is a Digi-Key ordering number. The manufacturer MPN should be DG403DYZ; DG403DYZ-ND should be stored as the Digi-Key Part Number if both properties are available.
  • Change Manufacturer Part Number to DG403DYZ.
  • Add Digi-Key Part Number = DG403DYZ-ND.
  • Rewrite terminal designators/pin numbers to match the datasheet pinout table above.
  • Add/rename missing IN3 and IN4 controls and remove the two false NC terminals.
  • Re-check footprint dimensions against the Renesas package drawing after pin mapping is fixed.
