General Description
The HT6P20x2T3 is a CMOS LSI encoder designed for remote control system applications. It encodes 24 bits of information and then serially transmits it via the PAOUT pin upon receipt of transmission enable (DATA pins: D0~D4) signals. In addition, the device offers various packaging for flexible combination of address/data so as to meet the needs of various applications. Its address/data is transmitted together with the anti-code bits using an RF transmission medium upon receipt of a trigger signal.
