General Description

The 3¹⁸decoders are a series of CMOS LSIs for

remote control system applications. They are

paired with the 3¹⁸series of encoders. For

proper operation, a pair of encoder/decoder pair

with the same number of address and data for-

mat should be selected (refer to the encoder/de-

coder cross reference tables).

The 3¹⁸series 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 se-

rial input data twice continuously with its local

address. If no errors or unmatched codes 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 transmis-

sion.

The 3¹⁸decoders 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 ad-

dress pin whose range is from 8 to 18. In addi-

tion, the 3¹⁸decoders provide various

combinations of address/data number in differ-

ent packages.
