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 en-  
coder/decoder cross reference tables).  
The 318 series of decoders receives serial ad-  
dress 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 de-  
coded 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 information that consists of N bits of address  
and 18–N bits of data. To meet various applica-  
tions 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 com-  
binations of address/data number in different  
packages.
