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 3 12 encoders offer flexible combinations of pro- grammable 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.

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 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.

But for the Data trigger type, it is enabled by applying a low signal to one of the data pins D8~D11.
