HT12E + HT12D REMOTE CONTROL RF433 IC

Description: HT12E:  The HT12E encoders are a series of CMOS LSIs for remote control system applications. They are capable of encoding information which consists of N address bits and 12 N data bits. Each address/ data input can be set to one of the two logic states. The programmed addresses/data are transmitted together with the header bits via an RF or an infrared transmission medium upon receipt of a trigger signal. The capability to select a TE trigger on the HT12E or a DATA trigger on the HT12A further enhances the application flexibility of the 212 series of encoders. The HT12A additionally provides a 38kHz carrier for infrared systems. HT12D: The HT12D decoders are a series of CMOS LSIs for remote control system applications. They are paired with Holtek s HT 12E series of encoders (refer to the encoder/decoder cross reference table). For proper operationa pair of encoder/decoder with the same number of addresses and data format should be chosen. The decoders receive serial addre
