HT2040A General Description
The HT2040A is a low cost, low power CMOS LSI chip designed for use in Christmas lighting control products. It provides 4 SCR outputs to control the lamps. The lamps can display up to 10 different groups of lighting patterns, where each pattern or pattern group is chosen by appropriate input keys.
The available 10 groups of lighting patterns can all be displayed automatically or sequentially using a single key. (12 patterns and 10 pre-programmed groups are provided by default.)
The internal PLL circuit allows synchronized control of the SCRs at either 50Hz or 60Hz AC supply voltage.
