General Description
The 312 encoders are a series of CMOS LSIs for remote control system applications. They are capable of encoding 12 bits of information which consists of N address bits and 12-N data bits. Each address/data input is externally trinary programmable if bonded out. They are otherwise set floating internally. Various packages of the 312 encoders offer flexible combinations of programmable address/data which meet various applications. The programmable address/data is transmitted together with the header bits via an RF or an infrared transmission medium upon receipt of a trigger signal. A TE (HT6010) or a DATA (HT6012/HT6014) trigger can be selected for application flexibility.

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, active 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 Waveform Each programmable address/data pin can be externally set to one of the following three logic states:
fO
SC
"O n e " "Z e ro " "O p e n " A d d r e s s /D a ta B it
Address/Data Bit Waveform The Open 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 high, low, or floating. 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. Address/Data Bits Part No. 0 HT6010 HT6012 HT6014 A0 A0 A0 1 A1 A1 A1 2 A2 A2 A2 3 A3 A3 A3 4 A4 A4 A4 5 A5 A5 A5 6 A6 A6 A6 7 A7 A7 A7 8 AD8 A8 D8 9 AD9 A9 D9 10 AD10 D10 D10 11 AD11 D11 D11
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.
