HD151012 Datasheet (Hitachi Semiconductor) - 8-bit Binary Programmable Counter with Synchronous Preset Enable

HD151012 - 8-bit Binary Programmable Counter with Synchronous Preset Enable

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
