General Description
The 3
12
encoders 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 ex-
ternally 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 appli-
cations. 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.

Functional Description
Operation
The 3
12
series of encoders begin with a four (HT6010) or a one (HT6012/HT6014) word transmission cycle upon receipt
of a transmission enable (TE for the HT6010 or D8~D11 for the HT6012/HT6014, active low). 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.
