74LS161 4-Bit Synchronous Binary Counter IC (74161)

74LS161 4-Bit Binary Counter IC circuit designed as a synchronous reversible up-down counter. These synchronous, presettable counters provide an internal carry look-ahead feature for application in high-speed counting designs. The carry output decoded via a NOR gate. Thus preventing spikes during the normal counting mode of operation 74LS161 comes with a 4-bit binary counter in…
