DM74LS390N	Dual 4-Bit Decade Counter General Description Each of these monolithic circuits contains eight master-slave flip-flops and additional gating to implement two individual four-bit counters in a single package. The DM74LS390 incorporates dual divide-by-two and divideby-five counters, which can be used to implement cycle leng	FAIRCHILD 仙童半导体	FAIRCHILD
