THVD1450DR Footprint Audit


READ ONLY audit existing THVD1450DR part. No mutations, repairs, substitutions, publishes, or document writes. Inspect ACTUAL physical footprint pad count, pad mappings, dimensions and coordinates (not indexed 14-SOIC tag). Compare with TI THVD1450DR D SOIC8 datasheet https://www.ti.com/lit/ds/symlink/thvd1450.pdf using query_datasheet official evidence. Report eight-pad SOIC geometry PASS/FAIL or specific unavailable inspection blocker. Include actual pad coordinate/size evidence, pitch and row span, pin mappings, body if available. Only inspect your active part project. Report concisely to parent; gateway must remain untouched.
I’ll inspect the active part’s actual pad geometry and pin mappings, then compare them with TI’s SOIC-8 drawing. This audit is read-only.
PASS: actual eight-pad SOIC geometry and pin mapping—not SOIC-14; FAIL: exact TI example-land-pattern match. Actual pad centers in mm (Flux coordinates): 1/R (−1.91,−2.77), 2/RE̅ (−0.63,−2.77), 3/DE (+0.63,−2.77), 4/D (+1.90,−2.77), 5/GND (+1.90,+2.77), 6/A (+0.63,+2.77), 7/B (−0.63,+2.77), 8/VCC (−1.91,+2.77); all eight pads are 0.59 × 2.05 mm, adjacent pitches 1.28/1.26/1.27 mm, opposing-row centers 5.54 mm, with mappings matching TI.
TI D0008A’s example specifies 0.60 × 1.55 mm pads, 1.27 mm pitch, 5.40 mm row spacing—so this footprint has longer pads and wider row spacing, not automatically an incompatible footprint; verified evidence handle: dsq_f6ceac5df5424faed02c, keys ds1–ds4.
The footprint payload and eight live pad nodes agree after converting stored meter-valued geometry to mm; its silkscreen rectangle is 5.06 × 3.04 mm, but actual body dimensions were unavailable (packageSize=0), and no project mutations, document writes, or gateway inspection occurred.
