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~D7) 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.

Functional Description
Normal Operation
The HT6P20X encodes and transmits address/data to a decoder upon receipt of a trigger signal. The address codes of
the HT6P20A are always transmitted as long as power (VDD) is supplied. The transmission function of the HT6P20B/D
is enabled by the D0~D7 pins (active low). The following is the transmission timing of the HT6P20X:

The HT6P20A/B/D detects the logic state of the internal programmed address and the external data pins, and then trans-
mits the detected information during the code period. Each address/data bit can be set to one of the following two logic
