Connect pins AD8–AD11 (Data pins) to logic toggles or SPST switches pulled up to VCC.
If you can't find a library, creating your own custom component in Proteus ensures you have complete control over the "extra quality" of the model. While it requires more work, it guarantees an accurate simulation. ht12e and ht12d proteus library file download extra quality
resistor between these two pins to establish the recommended encoding frequency. Connect pins AD8–AD11 (Data pins) to logic toggles
This 18-pin IC converts 12-bit parallel inputs (consisting of 8 address bits and 4 data bits) into a secure serial data stream. It features a Transmission Enable ( TE ) pin to trigger data transmission. resistor between these two pins to establish the

This happens if you downloaded a schematic symbol without its accompanying .DLL or simulation model file. Ensure your source file is marked as a "VSM Simulation Model" rather than just a PCB footprint.
