HT-12E DIP

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 12-N data bits. Each ad-dress/data input can be set to one of the two logic states. The programmed addresses/data are transmitted together with the header bitsvia 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 DATAtrigger on the HT12A further enhances the ap-plication flexibility of the 212 series of encoders.The HT12A additionally provides a 38kHz car-rier for infrared systems
