General Description
The 312decoders are a series of CMOS LSIs for
remote control system applications. They are
paired with 3
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).

encoders that are transmitted by a carrier using an RF or an IR transmission medium. Then
it compares the serial input information twice

or unmatched codes are encountered, the input
data codes are decoded and transferred to the
output pins. The VT pin also goes high to indicate a valid transmission.

The 3
ing 12 bits of information that consists of N bits
of address and 12-N bits of data. To meet various 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.
