The HT12D Decoder ICs are series of CMOS LSIs for Remote Control system applications. These ICs are paired with each other. For proper operation a pair of encoder/decoder with the same number of address and data format should be selected (HT12E is paired with HT12D). The Decoder receive the serial address and data, transmitted by a carrier using an RF transmission medium and gives output to the output pins after processing the data.
