Features

HT6P20D: 16-pin DIP/NSOP package

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.
