Use them only for learning and personal simulation. Do not use them for commercial product design without proper licensing from Labcenter Electronics and Holtek.
⚠️ You cannot simulate actual RF transmission. Instead, connect DOUT of HT12E directly to DIN of HT12D via a wire or digital net. This verifies encoding/decoding logic.
encodes 12 bits of parallel data into a serial stream for transmission, while the decodes that serial stream back into parallel data. Instructables Download and Installation Guide How to Import HT12E and HT12D IC into Proteus 8
