Converts 4-bit parallel data into a serial format for transmission. It features 8 address bits, allowing up to 256 secure combinations to prevent signal interference.
Connect a 1MΩ resistor across the OSC1 and OSC2 pins of the HT12E. Connect a 51kΩ resistor across the OSC1 and OSC2 pins of the HT12D.

One mark of a truly library is the ability to change the oscillator frequency. The default simulation model uses a lookup table. To customize:
Complete Guide to HT12E and HT12D Proteus Library Simulation
Look for a high-quality "HT12E HT12D Proteus Library" package online. The download package usually comes as a .zip or .rar archive containing two vital files: HT12E_HT12D.LIB HT12E_HT12D.IDX Step 2: Locate Your Proteus Library Directory
Connect all pins to Ground (GND) to set the address to 00000000 .
Connect pins 1 through 8 (A0 to A7) of both the HT12E and HT12D to (Ground). Matching the addresses on both chips ensures that the decoder accepts the encoder's signal stream. 2. Oscillator Configuration (Crucial Step)
Toggle the LOGICSTATE inputs connected to the HT12E encoder.
