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 en-  
coder/decoder pair with the same number of address  
and data format should be selected (refer to the en-  
coder/decoder cross reference tables).  
are encountered, the input data codes are decoded and  
then transferred to the output pins. The VT pin also goes  
high to indicate a valid transmission.  
The 318 decoders are capable of decoding 18 bits of in-  
formation that consists of N bits of address and 18-N  
bits of data. To meet various applications they are ar-  
ranged 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 combi-  
nations of address/data number in different packages.  
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
