Applications
* the Clocked Carry (CC) output is provided. The CC output is normally HIGH. When CEP, CET, and TC are LOW, the CC output will go LOW when the clock next goes LOW and will stay LOW until the clock goes HIGH again, as shown in the CC Truth Table. When the Output Enable (OE) is LOW, the parallel data o
