DM74S161 Applications
* without additional gating Instrumental in accomplishing this function are two count-enable inputs and a ripple carry output Both countenable 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 high-le
