Holtek Semiconductor HT6P20A
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: D 0 ~ D 7 < 1 w o rd E n c o d e r D O U T > 1 w o rd Transmission timing A complete code word of the HT6P20D consists of 3 periods as shown below.| Part No. | HT6P20A |

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~D7) signals. The combination of address and data bits of the HT6P20X is designed using one time programmable process. In addition, the chip offers various packaging for flexible combination of programmable address/data so as to meet various applications.
