Description: Synchronous 4-Bit Counters

Features

* Y Y Y Y Y Y Synchronously programmable Internal look-ahead for fast counting Carry output for n-bit cascading Synchronous counting Load control line Diode-clamped inputs Connection Diagram Dual-In-Line Package TL F 6551
* 1 Order Number DM54161J DM54161W DM74161N or DM74163N See NS Packa

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
