They are paired with 312 series 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). or unmatched codes are encountered, the input data codes are decoded and transferred to the output pins. The VT pin also goes high to indicate a valid transmission. The 312 series of decoders are capable of decoding 12 bits of information that consists of N bits of address and 12-N bits of data. To meet various 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. The 312 series of decoders receive serial address and data from its corredponding series of encoders that are transmitted by a carrier using an RF or an IR transmission medium. Then it compares the serial input information twice continuously with its local address.

They are paired with 312series of encoders. The decoders receive data transmitted by the encoders and interpret the first N bits of the code period as addresses and the last 12-N bits as data (where N is the address code number). A signal on the DIN pin then activates the oscillator which in turn decodes the incoming address and data. The decoders check the received address twice continuously. If all the received address codes match the contents of the decoder¢s local address, the 12-N bits of data are decoded to activate the output pins and the VT pin is set high indicating a valid transmission. That will last until the address code is incorrect or no signal is received. P o w e r o n S ta n d b y m o d e N o D is a b le V T & ig n o r e th e r e s t o f th is w o r d A re C o d e in ?
