Description
The HD151012 has 8-bit binary down counter and D-type Flip Flop. The counter can set up to max 256
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.
