1 / 10 page  312 Series of Decoders 1 December 13, 1999 General Description The 312decoders are a series of CMOS LSIs for remote control system applications. They are paired with 312series of encoders. For proper operation a pair of encoder/decoder with the same number of address and data format should be selected (refer to the encoder/decoder cross reference tables). The 312 series of decoders receive serial address and data from its corredponding series of encoders that are transmitted by a carrier us- ing an RF or an IR transmission medium. Then it compares the serial input information twice continuously with its local address. If no errors or unmatched codes are encountered, the input data codes are decoded and transferred to the output pins. The VT pin also goes high to indi- cate a valid transmission. The 312 series of decoders are capable of decod- ing 12 bits of information that consists of N bits of address and 12-N bits of data. To meet vari- ous applications they are arranged to provide a number of data pins ranging from 0 to 4 and an address pin ranging from 8 to 12. Thus, various combinations of address/data number are available in different packages.
