Description: HT12A Encoder

HT12A HT-12A 212 Series Remote Control Encoder IC DIP-18 Integrated Circuit Dual In Line Package IC Electrical Circuitry & Parts

The 2¹² 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 12N 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.
