To work with the HT12E and HT12D encoder and decoder ICs in Proteus, you'll need to have the appropriate library files integrated into your Proteus environment. These ICs are commonly used in remote control systems, where the HT12E is used for encoding and the HT12D for decoding signals.
: For PCB design specifically, you can download verified symbols and 3D models from How to Install the Library Files Once you have downloaded the file, follow these steps to add them to your software: Insert HT12E and HT12D in proteus - Forum for Electronics 8 Jan 2013 — ht12e and ht12d proteus library file download link
: Some older libraries (for Proteus 7) may not be fully compatible with Proteus 8.12 or later without manual adjustment. To work with the HT12E and HT12D encoder
