UNISONIC TECHNOLOGIES CO., LTD UT912D DECODERS FOR REMOTE CONTROLLER  DESCRIPTION The UTC UT912D of CMOS LSIs for remote control system applications are paired with UTC UT912E (refer to the encoder/decoder cross reference table) and is capable of decoding information which consists of N address bits and 12-N data bits. For proper operation, a pair of encoder/decoder with the same number of addresses and data format should be chosen. The UTC UT912D also is arranged to provide 8 address bits and 4 data bits. The decoders receive serial addresses and data from a programmed UTC UT912E of encoders that are transmitted together with the header bits by a RF or an infrared transmission medium upon receipt of a trigger signal.
