HOLTEK HT12E Datasheet & Stock

The HT12E is a 2^12 encoder in 18 pin DIP package. This is CMOS LSI for remote control system applications. It is 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 header bits via an RF or an infrared transmission medium upon receipt of trigger signal.
