TL331LV
Public Unreviewedby barrett-land
TL331LV - single low-voltage comparator, SOT-23-5, with REVERSED input pinout (IN- = pin 1, IN+ = pin 3). Canonical adom-lbr JSON + KiCad symbol/footprint/3D. Used on the USB3-to-Ethernet Data-Only Molecule.

That makes the two parts **mechanically interchangeable drop-ins whose comparator polarity is opposite**, so an unintended substitution silently inverts the decision and still passes AOI. Used deliberately here: fitting the TL331LV in an LMV331 footprint inverts the CC1/CC2 orientation decision with **zero layout change**, which is how the molecule's USB-C orientation detection was corrected.
