General Description
The 3¹² encoders are a series of CMOS LSIs for remote control system applications. They are capable of encod ing 12 bits of information which consists of N address bits and 12-N data bits. Each address/data input is externally trinary programmable if bonded out. They are otherwise set floating internally. Various packages of the 312 encoders offer flexible combinations of programmable address/data which meet various applications. The programmable address/data is transmitted together with the header bits via an RF or an infrared transmission medium upon receipt of a trigger signal. A TE (HT6010) or a DATA (HT6012/HT6014) trigger can be selected for application flexibility.
