HT6030

TThe 3¹² decoders HT6030 are a series of CMOS LSIs for remote control system applications. 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).

The 3¹² series of decoders HT6030 receive serial address and data from its corresponding 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. 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 indicate a valid transmission.

The 3¹² series of decoders HT6030 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.
