They are capable of encoding 18 bits of information which consists of N address bits and 18-N data bits. Each address/data input is externally trinary programmable if bonded out. It is otherwise set floating internally. Various packages of the 318 encoders offer flexible combinations of programmable address/data to meet various application needs. 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. The capability to select a TE trigger type or a DATA trigger type further enhances the application flexibility of the 318 series of encoders.

This cycle will repeat itself as long as the transmission enable (TE or D12~D15) is held high. Once the transmission enable falls low, 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 logic ²high², ²low², or ²floating². If a transmission enable signal is applied, the encoder scans and transmits the status of the 18 bits of address/data serially in the order A0 to AD17 for the HT600/HT680 and A0 to D15 for the HT6207. There are some packaging limitations. For example t he 18-pin DIP HT680, offers four external data bits and eight external address bits. The remaining unpackaged bits or dummy codes are treated as floating for A0~AD17 or as pull-low for D12~D15. During an information transmission these bits are still located in their original position. But if the trigger signal is not applied, the chip only consumes a standby current which is less than 1mA. Rev. 1.10 5 January 24, 2003 HT600/HT680/HT6207 The address pins are usually preset to transmit data codes with particular security codes by the DIP switches or PCB wiring, while the data is selected using push buttons or electronic switches.

Transmission Enable For the TE trigger type of encoders, transmission is enabled by applying a high signal to the TE pin. But for the Data trigger type of encoders, it is enabled by applying a high signal to one of the data pins D12~D15.
