They are paired with the 318 series of encoders. For proper operation, a pair of encoder/decoder pair with the same number of address and data format should be selected (refer to the encoder/decoder cross reference tables). The 318 series of decoders receive serial address and data from that series of encoders that are transmitted by a carrier using an RF or an IR transmission medium. It then compares the serial input data twice continuously with its local address. If no errors or unmatched codes are encountered, the input data codes are decoded and then transferred to the output pins. The VT pin also goes...
