General Description
The HT6026 is a CMOS LSI encoder designed for
use in remote control system. It is capable of
encoding 9 bits of information which consists of N
address bits and 9–N data bits. Each address/data
input is externally trinary programmable by ex-
ternal switches. The programmable address/data

is transmitted along with the header bits via an
RF or an infrared transmission medium upon
receipt of a trigger signal (TE).
The HT6026 is pin compatible with the
MC145026.
