Applications

* without additional gating. Instrumental in accomplishing this function are two count-enable inputs and a ripple carry output. Both count-enable inputs (P and T) must be HIGH to count, and input T is fed forward to enable the ripple carry output. The ripple carry output thus enabled will produce a HI
