General Description

The 312encoders are a series of CMOS LSIs for remote
control system applications. They are capable of encod
ing 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

12

encoders offer flexible combinations of pro-

­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.

Address/Data Waveform

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

f

O S C

" O n e "

" Z e r o "

" O p e n "

A d d r e s s / D a t a B i t

Address/Data Bit Waveform

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,or²floating². If a transmission en
able 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 V

The address pins are usually preset so as to transmitdata codes with their own particular security codes by the DIP switches
or PCB wiring, while data is selected using push button or electronic switches.

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 trig

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