The HT12D is the counterpart decoder IC. It receives the serial data stream from an RF Receiver module. It decodes the data back into parallel bits. Crucially, it compares the received address bits with its own locally set address bits. If they match, it triggers the VT (Valid Transmission) pin and outputs the 4 data bits to control external devices (like motors, relays, or LEDs).

If, after multiple attempts, you cannot get the HT12E/HT12D to simulate correctly, consider these alternatives: The HT12D is the counterpart decoder IC
The HT12E and HT12D library files you download are or user-created schematic symbols with SPICE simulation code. They are not official Holtek models. Labcenter Electronics does not provide technical support for third-party libraries. Therefore: Crucially, it compares the received address bits with
