IC HT12E Encoder For Remote Control Systems Dip-18 (Per Piece)

The HT12E is a 12-bit series encoder IC designed for remote control applications. It is widely used in RF and IR communication systems. Paired with the HT12D decoder, it allows simple transmission and reception of 12-bit parallel data in serial form. The 12-bit data consists of 8 address bits and 4 data bits, enabling security coding and support for multiple receivers with the same transmitter.
