18 Dip HT12E RF Encoder IC is a series of CMOS LSIs for remote control system applications. 18 Dip HT12E RF Encoder IC is 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 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 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.
We have also PIC18F2550 USB Microcontroller, PIC18f452 Microcontroller, PIC18F452 Microcontroller etc.
