Address/data waveform

Each programmable address/data pin can be externally set to one of the following three logic states:

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

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.
