The HT 12E encoder ICs are series of CMOS LSIs for remote control system applications. They are capable of encoding 12 bits of information consisting of N address bits and 12-N data bits. Each address / data entry is externally trinary programmable if it is linked.
HT 12D integrated circuits are LSI CMOS series for remote control applications. These integrated circuits are paired together. For correct operation a pair of encoders / decoders with the same number of addresses and data format must be selected. The decoder receives the serial address and the data from its corresponding decoder, transmitted by a carrier using an RF transmission medium and output to the output pins after processing the data.
