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-

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:
