General Description
The 3
12
decoders are a series of CMOS LSIs for
remote control system applications. They are
paired with 3
12
series of encoders. For proper
operation a pair of encoder/decoder with the
same number of address and data format
should be selected (refer to the encoder/decoder
cross reference tables).
The 3
12
series of decoders receive serial address
and data from its corredponding series of
encoders that are transmitted by a carrier us-
ing an RF or an IR transmission medium. Then
it compares the serial input information twice
continuously with its local address. If no errors
or unmatched codes are encountered, the input
data codes are decoded and transferred to the
output pins. The VT pin also goes high to indi-
cate a valid transmission.
The 3
12
series of decoders are capable of decod-
ing 12 bits of information that consists of N bits
of address and 12-N bits of data. To meet vari-
ous applications they are arranged to provide a
number of data pins ranging from 0 to 4 and an
address pin ranging from 8 to 12. Thus, various
combinations of address/data number are
available in different packages.
