Functional Description
Operation series encoders begins three-word transmission cycle upon receipt transmission enable HT600/HT680 D12~D15 HT6207, active high). This cycle will repeat itself long transmission enable D12~D15) held high. Once transmission enable falls low, encoder output completes final cycle then stops shown below.

Composition information
Address/Data Waveform Each programmable address/data externally following three logic states:
Address/Data waveform state data input interpreted logic decoders since decoder output only have states. Address/Data Programming (Preset) status each address/data individually preset logic transmission enable signal applied, encoder scans transmits status bits address/data serially order AD17 HT600/HT680 HT6207. There some packaging limitations. example 18-pin HT680, offers four external data bits eight external address bits. remaining unpackaged bits dummy codes treated floating A0~AD17 pull-low D12~D15. During information transmission these bits still located their original position. trigger signal applied, chip only consumes standby current which less than 1mA.
