General Description
The 3
12
encoders are a series of CMOS LSIs for
remote control system applications. They are ca-
pable of encoding 12 bits of information which
consists of N address bits and 12-N data bits.
Each address/data input is externally trinary
programmableifbondedout.Theyareotherwise
set floating internally. Various packages of the
3
12
encoders offer flexible combinations of
programmable address/data which meet vari-
ous applications. The programmable ad-
dress/dataistransmittedtogetherwiththeheader
bitsviaanRForaninfraredtransmissionmedium
upon receipt of a trigger signal. A TE (HT6010) or
a DATA (HT6012/HT6014) trigger can be se-
lectedforapplicationflexibility.
Features
