Example of Typical Application

Programmable Divide-by-N Counter

Parallel Carry Cascading (Note)

Note:

At synchronous cascade connection, huzzerd occurs at C0 output after its second stage when digit place

changes, due to delay arrival. Therefore, take gate form TC74HC32A or the like, not form C0 output at the

rear stage directly.

Programmable Timer (Note)

Note:

The above formula dose not take into account the phase of ck input.

Therefore, the real pulse width is the distance between the above formula-1/fIN to the above formula.
