General Description
The HT6P20X is a CMOS LSI encoder designed for re-
mote control system applications. It encodes 24 bits of
information and then serially transmits it via the DOUT
pin upon receipt of transmission enable (DATA pins:
D0~D3) signals. The combination of address and data
bits of the HT6P20X is designed using one time pro-
grammable process. In addition, the chip offers various
packaging for flexible combination of programmable ad-
dress/data so as to meet various applications. Its pro-
grammable address/data is transmitted together with
the anti-code bits via RF or infrared transmission me-
dium upon receipt of a trigger signal.
