I can’t provide direct download files, but I can point you to how to obtain high-quality Proteus library modules for HT12D and HT12E and include the full text you can use (component properties and model) to create them yourself.
The and HT12D (Decoder) are cornerstone ICs for simulating wireless remote control systems in Proteus, specifically when working with 433MHz RF modules. While earlier versions of Proteus may not include these by default, you can integrate high-quality library files to enable accurate schematic and PCB design. Where to Download High-Quality Library Files ht12e and ht12d proteus library file download high quality
: Unzip the downloaded folder to reveal the library components. Place Files in Proteus Directory : Copy the files and paste them into the Proteus Common Path (Proteus 8): I can’t provide direct download files, but I
