General Description
The 312 encoders are a series of CMOS LSIs for
remotecontrolsystemapplications. Theyareca-
pable of encoding 12 bits of information which
consists of N address bits and 12-N data bits.
Each address/data input is externally trinary
programmableifbondedout.Theyareotherwise
set floating internally. Various packages of the
312 encoders offer flexible combinations of
programmable address/data which meet vari-
ous applications. The programmable ad-
dress/dataistransmittedtogetherwiththeheader
bitsviaanRForaninfraredtransmissionmedium
upon receipt of a trigger signal. A TE (HT6010) or
a DATA (HT6012/HT6014) trigger can be se-
lectedforapplicationflexibility.

312 Series of Encoders
Functional Description
Operation
The 312 series of encoders begin with a four (HT6010) or a one (HT6012/HT6014) word transmission
cycle upon receipt of a transmission enable (TE for the HT6010 or D8~D11 for the HT6012/HT6014, ac-
tive low). This cycle will repeat itself as long as the transmission enable (TE or D8~D11) is held low.
Once the transmission enable returns high the encoder output completes its final cycle and then stops
as shown below.

Address/Data bit waveform
The ²Open² state data input is interpreted as logic high by the decoder since its output has only two
states.
Address/data programming (preset)
The status of each address/data pin can be individually preset to a logic ²high², ²low², or ²floating². If
a transmission enable signal is applied, the encoder scans and transmits the status of the 12 bits of
address/data serially in the order A0 to AD11 for the HT6010 and A0 to D11 for the HT6012/HT6014.
If the trigger signal is not applied, the chip only consumes a standby current which is less than 1mA
(for VDD=5V).
The address pins are usually preset so as to transmit data codes with their own particular security codes
by the DIP switches or PCB wiring, while data is selected using push button or electronic switches.
Address/Data sequence
The following table provides the position of the address/data sequence for various models of the 312
series encoders. A correct device should be selected according to the requirements of the individual
address and data.

Transmission enable
For the TE trigger type of encoders, transmission is enabled by applying a low signal to the TE pin.
But for the Data trigger type, it is enabled by applying a low signal to one of the data pins D8~D11.
