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

312 Series of Decoders
Functional Description
Operation
Flowchart
The 312 series of decoders provide various com-
binations of address and data pins in different
packages. They are paired with 312series of
encoders. The decoders receive data transmit-
ted by the encoders and interpret the first N
bits of the code period as addresses and the last
12-N bits as data (where N is the address code
number). A signal on the DIN pin then acti-
vates the oscillator which in turn decodes the
incoming address and data. The decoders check
the received address twice continuously. If all
the received address codes match the contents
of the decoder¢s local address, the 12-N bits of
data are decoded to activate the output pins
and the VT pin is set high indicating a valid
transmission. That will last until the address
code is incorrect or no signal is received.

The oscillator is disabled in the standby state
and activated as long as a logic ²high² signal is
applied to the DIN pin. i.e., the DIN pin should
be kept ²low² if there is no signal input.
