A search within the PDF for the term “LAH” yields no matches. Therefore, while the Microchip forum post confidently states “there is a new schematic uploaded,” it does not actually contain any reference to “LAH103P.” The most plausible explanation is that the forum thread was mis‑tagged or that the PDF was intended for a different discussion.

Because the old schematic showed an open-collector output, technicians added pull-up resistors to 5V or 3.3V. The shows this is now unnecessary and harmful. The output is a true voltage output. Adding a pull-up will cause current sinking conflicts and non-linear readings.
