SN74AS161 counter equivalent, synchronous 4-bit decade and binary counter.
without additional gating. ENP and ENT inputs and a ripple-carry (RCO) output are instrumental in accomplishing this fun.
These synchronous, presettable, 4-bit decade and binary counters feature an internal carry look-ahead circuitry for application in high-speed counting designs. The SN54ALS162B is a 4-bit decade counter. The ’ALS161B, ’ALS163B, ’AS161, and ’AS163 devi.
