The HD151011 has BCD decimal two digits down counter and D-type Flip Flop. The counter can set up to max 99 counts and synchronous preset (SPE) input can preset the data. When the count value is 0, the next clock pulse presets the data to invert the output. D-type Flip Flop takes the counter output as clock pulse, whose data is transferred to output at the rise edge. It is applied to generate AC signal for STN type liquid crystal and general-use divider.
