General Description
The HT6P20X is a CMOS LSI encoder designed for remote 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 address/data so as to meet various applications. Its programmable address/data is transmitted together with
the anti-code bits via RF or infrared transmission medium upon receipt of a trigger signal.

Functional Description
Normal Operation
The HT6P20X encodes and transmits address/data to a decoder upon receipt of a trigger signal. The transmission
function of the HT6P20B/D is enabled by the D0~D3 pins (active low). The following is the transmission timing of the
HT6P20X:
