*Note: Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only. Functional operation of this device at these or any other conditions above those indicated in the operational sections of this specification is not implied and exposure to absolute maximum rating conditions for extened periods may affect device reliability.

The 3¹⁸ decoders HT602L are a series of CMOS LSIs for remote control system applications. 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 HT602L receives 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 nd then transferred to the output pins. The VT pin also goes high to indicate a valid transmission.

The 3¹⁸ decoders HT602L are capable of decoding 18 bits of information that consists of N bits of address and 18N bits of data. To meet various applications they are arranged to provide a number of data pins whose range is from 0 to 8 and an address pin whose range is from 8 to 18. In addition, the 318 decoders provide various combinations of address/data number in different packages.
