General Description

The 318 decoders 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).
