General Description
2. General Description
The IT7001M/IT7001N consists of 8-bit binary down counter and D-type Flip Flop. The counter can set up to
max 256 counts and synchronous preset (SPE_N) 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 rising edge. It is applied to generate AC signal for STN-type liquid
crystal and divider for general usage.
