Run the simulation. When the 38 kHz signal is active, the output pin should go LOW (0V). When no 38 kHz signal, output stays HIGH (5V).
If you cannot find a working library, you can create a using Proteus’s “Schematic Model” feature with a 555 timer and logic gates. However, this is tedious. A much simpler alternative is to use the TSOP4838 model (some Proteus versions include it) and rename it—electrically, it is identical in function.

that frequently includes TSOP series models. It provides the files needed for simulation. SnapMagic (formerly SnapEDA)

💡 If you cannot find ProgramData , enable “Show hidden files” in Windows Explorer.
: A free CAD library where you can search for the TSOP1738 by part number to download symbols, footprints, and occasionally simulation models directly compatible with Proteus. GitHub - Proteus_Library If you cannot find a working library, you
(Note: The download typically includes a TSOP1738.IDX and TSOP1738.LIB file, and sometimes a project example file.)

For Proteus users, the library above remains the best practical solution.
